<h2 id="abstract">Abstract</h2>

<p property='dc:abstract'>XHTML-Print is a member of the family of XHTML languages defined by the <cite>Modularization of <abbr title="Extensible HyperText Markup Language">XHTML</abbr></cite> [<a
href="#ref_xhtmlmod">XHTMLMOD</a>]. It is designed to be appropriate for printing from mobile devices to low-cost printers that might not have a full-page buffer and that generally print from
top-to-bottom and left-to-right with the paper in a portrait orientation. XHTML-Print is also targeted at printing in environments where it is not feasible or desirable to install a printer-specific
driver and where some variability in the formatting of the output is acceptable.</p>

<h2 id="status">Status of This Document</h2>

<p><em>This section describes the status of this document at the time of its publication. Other documents may supersede this document. A list of current W3C publications and the latest revision of
this technical report can be found in the <a href="http://www.w3.org/TR/">W3C technical reports index</a> at http://www.w3.org/TR/.</em></p>

<p>All sections of this document are normative unless noted as informative.</p>

<p>This document is a Recommendation of XHTML Print. It supercedes the <a href="http://www.w3.org/TR/2006/REC-xhtml-print-20060920">previous version</a>. The only substantive changes in this version
are the addition of an implementation of the markup language using XML Schema.</p>

<p>This document has been reviewed by W3C Members, by software developers, and by other W3C groups and interested parties, and is endorsed by the Director as a W3C Recommendation. It is a stable
document and may be used as reference material or cited from another document. W3C's role in making the Recommendation is to draw attention to the specification and to promote its widespread
deployment. This enhances the functionality and interoperability of the Web.</p>

<p>This document incorporates minor suggestions made during the <a href="http://www.w3.org/TR/2006/PR-xhtml-print-20060131/">XHTML-Print Proposed Recommendation</a> of 31 January 2006 and also
removes any requirement for CSS support; please see the public <a href="http://www.w3.org/MarkUp/2006/xhtml-print-pr-doc.html">disposition of comments</a> for details. Evidence of interoperability
between two implementations of this specification is documented in the <a href="http://www.w3.org/MarkUp/Test/xhtml-print/implementation/">Implementation Report</a>.</p>

<h1 typeof="bibo:Chapter" about="#s_intro" id="s_intro">1. Introduction</h1>

<p>All sections of this document are normative unless noted as informative.</p>

<h2 typeof='bibo:Chapter' about='#s1.1' id='s1.1'>1.1. <abbr title="Extensible HyperText Markup Language">XHTML</abbr> for Printing</h2>

<p>This section is informative.</p>

<p>This document specifies a simple XHTML based data stream suitable for printing as well as display. It is based on <cite>XHTML Basic</cite> [<a href="#ref_xhtmlbasic">XHTMLBASIC</a>]. Its targeted
usage is for printing in environments where it is not feasible or desirable to install a printer-specific driver and where some variability in the formatting of the output is acceptable. Throughout
this document this data stream is called "XHTML-Print."</p>

<p>XHTML-Print is designed to be appropriate for low-cost printers that might not have a full-page buffer and that generally print from top-to-bottom and left-to-right with the paper in a portrait
orientation. For other printers (i.e., those that print in another direction or orientation) a full-page buffer could be needed.</p>

<p>XHTML-Print is not appropriate when strict layout consistency and repeatability across printers are needed. The design objective of XHTML-Print is to provide a relatively simple, broadly
supportable page description format where content preservation and reproduction are the goal, i.e. "Content is King." Traditional printer page description formats such as PostScript or PCL are more
suitable when strict layout control is needed. XHTML-Print does not utilize bi-directional communications with the printer either for capabilities or status inquiries.</p>

<p>This document creates a set of conformance criteria for XHTML-Print. It provides a strong basis for consistent printing results without a detailed understanding of each individual printer's
characteristics.</p>

<p>The document type definition for <abbr title="Extensible HyperText Markup Language for Printing">XHTML-Print</abbr> is implemented based on the <abbr title="Extensible HyperText Markup Language">
XHTML</abbr> modules defined in <cite>Modularization of <abbr title="Extensible HyperText Markup Language">XHTML</abbr></cite> [<a href="#ref_xhtmlmod">XHTMLMOD</a>].</p>

<h2 typeof='bibo:Chapter' about='#s1.2' id='s1.2'>1.2. Terminology</h2>

<p>The keywords "<em title="MUST in RFC 2119 context" class="RFC2119">MUST</em>", "<em title="SHALL in RFC 2119 context" class="RFC2119">SHALL</em>", "<em title="MUST NOT in RFC 2119 context" class=

"RFC2119">RECOMMENDED</em>", "<em title="MAY in RFC 2119 context" class="RFC2119">MAY</em>", and "<em title="OPTIONAL in RFC 2119 context" class="RFC2119">OPTIONAL</em>" when used in this document
are to be interpreted as described in <cite>RFC 2119</cite> [<a href="#ref_rfc2119">RFC2119</a>]. However, for readability, these words might not appear in all uppercase letters in this
specification.</p>

<h2 typeof='bibo:Chapter' about='#s1.3' id='s1.3'>1.3. Design Rationale</h2>

<p>This section explains why certain <abbr title="HyperText Markup Language">HTML</abbr> features are not part of <abbr title="Extensible HyperText Markup Language for Printing">XHTML-Print</abbr>
and any special circumstances concerning a module and printing.</p>

<h3 typeof='bibo:Chapter' about='#s1.3.1' id='s1.3.1'>1.3.1. Script and Events</h3>

<p>Scripts, as programs that are executed in conjunction with a document, are not relevant to the printed page. However, documents can provide information as an alternative to a script. Therefore,
the script module is part of XHTML-Print. Scripts <em title="MUST NOT in RFC 2119 context" class="RFC2119">MUST NOT</em> be executed and their results <em title="MUST NOT in RFC 2119 context" class= 
"RFC2119">MUST NOT</em> be printed. If a <code>noscript</code> element is present, it contains alternate content that <em title="MUST in RFC 2119 context" class="RFC2119">MUST</em> be printed in
place of the content of the <code>script</code> element.</p>

<p>Events are not applicable to static, printed versions of a document. Therefore, the Intrinsic Events module is not part of XHTML-Print.</p>

<h3 typeof='bibo:Chapter' about='#s1.3.2' id='s1.3.2'>1.3.2. Presentation</h3>

<p>Many simple printers cannot print a wider variety of fonts than generic serif, sans serif and monospace. It is <em title="RECOMMENDED in RFC 2119 context" class="RFC2119">RECOMMENDED</em> that
style sheets be used to create a presentation that is appropriate for a particular category of printer. How printers are categorized, what those categories are, how a printer identifies itself as a
member of a category, and how style sheets are selectively applied based on category, is outside the scope of this document.</p>

<p>The <a href="http://www.w3.org/TR/xhtml-modularization/abstract_modules.html#s_presentationmodule">Presentation module</a> ([<a href="#ref_xhtmlmod">XHTMLMOD</a>], section 5.4.1) is supported to
provide simple control over basic font variants and rules.</p>

<h3 typeof='bibo:Chapter' about='#s1.3.3' id='s1.3.3'>1.3.3. Forms</h3>

<p><a href="http://www.w3.org/TR/xhtml-modularization/abstract_modules.html#s_sformsmodule">Basic <abbr title="Extensible HyperText Markup Language">XHTML</abbr> forms</a> ([<a href=
"#ref_xhtmlmod">XHTMLMOD</a>], section 5.5.1) are supported. Content developers <em title="SHOULD in RFC 2119 context" class="RFC2119">SHOULD</em> keep in mind that users might not be able to input
many characters from some devices (<abbr title="exempli gratia" xml:lang="lt">e.g.</abbr> from a mobile phone). Furthermore, developers are cautioned that a printer prints a static version of a form,
and the visual appearance of a form depends heavily on the implementation.</p>

<h3 typeof='bibo:Chapter' about='#s1.3.4' id='s1.3.4'>1.3.4. Tables</h3>

<p><a href="http://www.w3.org/TR/xhtml-modularization/abstract_modules.html#s_simpletablemodule">Basic <abbr title="Extensible HyperText Markup Language">XHTML</abbr> tables</a> ([<a href= 
"#ref_xhtmlmod">XHTMLMOD</a>], section 5.6.1) are supported, but tables can be difficult to format on very low resource devices. Furthermore, content developers are cautioned that in the Basic Tables
Module, nesting of tables is prohibited.</p>

<h3 typeof='bibo:Chapter' about='#s1.3.5' id='s1.3.5'>1.3.5. Frames</h3>

<p>Frames are not supported. Frames depend on a screen interface and therefore are not applicable to printers.</p>

<h3 typeof='bibo:Chapter' about='#s1.3.6' id='s1.3.6'>1.3.6. Attributes</h3>

<p><abbr title="Extensible HyperText Markup Language for Printing">XHTML-Print</abbr> is a member of the family of XHTML languages defined by <cite>Modularization of XHTML</cite> [<a href= 
"#ref_xhtmlmod">XHTMLMOD</a>]. Therefore, the elements and attributes in the modules that make up <abbr title="Extensible HyperText Markup Language for Printing">XHTML-Print</abbr> are all valid
constructs of the language. However, not all the attributes are applicable to a rendering of an XHTML-Print document in printed media, especially those that are integral to a dynamic display of the
document in a browser and the submission of a form. Furthermore, special attention is given to simple printers and some attributes are deemed too complex for a such a printer to render. These
attributes are treated as discretionary in that a conforming printer is not <em title="REQUIRED in RFC 2119 context" class="RFC2119">REQUIRED</em> to support them, but if a printer wishes to provide
that support, there are requirements stated for consistency in the implementation of extensions.</p>

<h3 typeof='bibo:Chapter' about='#s.1.3.7' id='s.1.3.7'>1.3.7 Character Model</h3>

<p>The W3C architectural specification <cite>Character Model for the World Wide Web 1.0</cite> [<a href="#ref_charmod">CHARMOD</a>] gives the <em title="RECOMMENDED in RFC 2119 context" class=
"RFC2119">RECOMMENDED</em> representation of characters in XHTML-Print. Authors of XHTML-Print producing applications should be aware that low cost printers might be limited in both processing power
and memory and therefore, that normalized utf-8 encoded documents could print more quickly than documents in other forms and encodings.</p>

<h2 typeof='bibo:Chapter' about='#s2.1' id='s2.1'>2.1. Document Conformance</h2>

<p>A conforming XHTML-Print document is a document that requires only the facilities described as mandatory in this specification. Such a document <em title="SHALL in RFC 2119 context" class=

<h2 typeof='bibo:Chapter' about='#s_charentities' id='s_charentities'>3.17 Character Entities</h2>

<p>XHTML-Print is in the family of XHTML document types, since it is created by combining XHTML modules. The character entities that are part of XHTML-Print are, therefore, defined in <a href= 
"http://www.w3.org/TR/xhtml-modularization/dtd_module_defs.html#a_dtd_xhtml_character_entities">XHTML Character Entities</a> ([<a href="#ref_xhtmlmod">XHTMLMOD</a>], Section F.1).</p>

<h1 typeof='bibo:Chapter' about='#s_howtouse' id="s_howtouse">4. How to Use <abbr title="Extensible HyperText Markup Language for Printing">XHTML-Print</abbr></h1>

<p>XHTML-Print inherits all the structure, encoding and other basic infrastructure specified by <cite>XHTML 1.0</cite> [<a href="#ref_xhtml1">XHTML1</a>]. The following sections describe and clarify
the application and usage restrictions of XHTML-Print.</p>

<h2 typeof='bibo:Chapter' about='#s.4.1' id='s.4.1'>4.1 Images</h2>

<p>This document specifies only one mandatory image format: baseline JPEG as defined in <cite>JPEG File Interchange Format</cite> [<a href="#ref_jpeg">JPEG</a>]. See <a href="#a_jpeg">Appendix A</a>
for a description of JPEG decoder requirements. Printers are not <em title="REQUIRED in RFC 2119 context" class="RFC2119">REQUIRED</em> to support:</p>

<ul>
<li>Embedded thumbnails</li>

<li>Rotation</li>

<li>Progressive rendering</li>
</ul>

<p>within the JFIF (JPEG File Interchange Format) and EXIF (Exchangeable Image File Format) files.</p>

<h3 typeof='bibo:Chapter' about='#s.4.1.1' id='s.4.1.1'>4.1.1 Recommended Attributes on the <code>img</code> and <code>object</code> Elements</h3>

<p>Because many printers create the page in a serial manner from top to bottom, it is important for the printer to know the size of images before retrieving the image data itself. This information is
then used to create portions of the page layout.<br />
</p>

<p>Therefore, the document <em title="SHOULD in RFC 2119 context" class="RFC2119">SHOULD</em> include the <code>height</code> and <code>width</code> attributes within the <code>img</code> or the
<code>object</code> element (or equivalent styling instructions). These attributes <em title="MAY in RFC 2119 context" class="RFC2119">MAY</em> be expressed as pixels or percentages within the <code>
img</code> or the <code>object</code> element. Percentages are relative to the parent element and not the page width or printable area.<br />
</p>

<h3 typeof='bibo:Chapter' about='#s.4.1.2' id='s.4.1.2'>4.1.2 Image Data</h3>

<p>[Informative]</p>

<p>In traditional Web-based applications of XHTML, image data is contained in a separate file on a Web server that the user agent retrieves.</p>

<p>However, there are circumstances where it is desirable to include the image data along with the rest of the print data. For example, some low cost, resource constrained clients might want to
include images in their print output but cannot afford to include an HTTP server. Furthermore, circumstances could require that all the print data be encapsulated in a single file for
transportability, avoiding firewall issues, etc. Therefore, conforming XHTML-Print printers <em title="MAY in RFC 2119 context" class="RFC2119">MAY</em> optionally support a format that contains both
a document and its referenced image data as well as the <em title="REQUIRED in RFC 2119 context" class="REQUIRED">REQUIRED</em> traditional format that contains only the document.</p>

<p>The format recommended for including image data along with xhtml-print markup is defined by <cite>RFC3391 - The MIME Application/Vnd.pwg-multiplexed Content-type</cite>. [<a href=
"#ref_mimempx">MIMEMPX</a>].</p>

<div>
<p>Including image data as defined in <cite>RFC2397 - The data URL scheme</cite> [<a href="#ref_rfc2397">RFC2397</a>] may be appropriate for printers capable of buffering large amounts of data, but
will not achieve the intended results for most cost- and memory-constrained printer UA's. Because this method normally encodes the binary image data using base64 encoding, a significant increase in
the size of the data transmitted will be experienced. This should be avoided over low speed connections. Printers supporting included data can support base64 encoding using the <code>img</code> or
<code>object</code> element.</p>

<div class="code" style="BORDER-RIGHT: 1px solid; PADDING-RIGHT: 4px; BORDER-TOP: 1px solid; PADDING-LEFT: 4px; PADDING-BOTTOM: 1px; BORDER-LEFT: 1px solid; PADDING-TOP: 1px; BORDER-BOTTOM: 1px
solid"><br />
&lt;object height="20 mm" width="20 mm" type="image/jpeg"<br />
&#160;&#160; data="data:image/jpeg;base64,aGh67Fghsapa0Hji7dfGSweTa . . ."&gt;<br />
&#160;&#160; Example Image &lt;/object&gt;<br />
</div>

or 

<div class="code" style="BORDER-RIGHT: 1px solid; PADDING-RIGHT: 4px; BORDER-TOP: 1px solid; PADDING-LEFT: 4px; PADDING-BOTTOM: 1px; BORDER-LEFT: 1px solid; PADDING-TOP: 1px; BORDER-BOTTOM: 1px
solid">&lt;img height="20 mm" width="20 mm" alt="Example Image"<br />
&#160;&#160; src="data:image/jpeg;base64,aGh67Fghsapa0Hji7dfGSweTa . . . " /&gt;</div>
</div>

<p>Mechanisms for determining whether or not a printer supports either of the above <em title="OPTIONAL in RFC 2119 context" class="RFC2119">OPTIONAL</em> document formats is outside the scope of
this specification.</p>

<h3 typeof='bibo:Chapter' about='#s.4.1.3' id='s.4.1.3'>4.1.3 Side-by-Side Images</h3>

<p>Low-cost printers today often have very little memory into which page data can be stored before being printed. As such, they may build and print the page in swaths on the fly from the top of the
page to the bottom. To enable the use of XHTML-Print in these low cost printers, some restrictions on the order of images contained in the XHTML-Print data stream must be added.</p>

<ol>
<li>If two or more images will be even partially side-by-side on the printed page (<em>i.e.,</em> a line across the short axis of the page will intersect more than one image), they <em title="SHOULD 
in RFC 2119 context" class="RFC2119">SHOULD</em> be included by reference; for example <code>&lt;img src="http://example.com/example.jpg"&gt;</code>. This allows the printer to get chunks of the
image, as it needs it, as it prints down the page. Interleaved or included image data, as discussed in <a href="#s.4.1.2">Section 4.1.2</a>, is discouraged.</li>

<li>An XHTML-Print conforming printer lacking sufficient buffer space to hold multiple side-by-side images <em title="MAY in RFC 2119 context" class="RFC2119">MAY</em> choose to reformat the layout
of the page to preserve content. Printers <em title="SHALL in RFC 2119 context" class="RFC2119">SHALL</em> attempt to preserve content when encountering side-by-side images that <em title="MAY in RFC 
2119 context" class="RFC2119">MAY</em> be impossible to print as specified within the XHTML-Print. Discarding the second and subsequent of the side-by-side images <em title="SHOULD in RFC 2119
context" class="RFC2119">SHOULD</em> be avoided unless preservation of content is best achieved by doing so. Other than attempting to best preserve content, this specification does not mandate any
specific behavior when encountering this situation. Clients providing images <em title="SHOULD in RFC 2119 context" class="RFC2119">SHOULD</em> order them from left-to-right top-to-bottom unless the
print direction is known to be otherwise.</li>
</ol>

<h2 typeof='bibo:Chapter' about='#s.4.2' id='s.4.2'>4.2 Style Sheets</h2>

<p>Conforming XHTML-Print printers <em title="SHALL in RFC 2119 context" class="RFC2119">SHALL</em> support both in-line and referenced style sheets within the <code>style</code> element or <code>
link</code> element in the <code>head</code> element of a document. Conforming XHTML-Print printers <em title="SHALL in RFC 2119 context" class="RFC2119">SHALL</em> also support the <code>
style</code> attribute (i.e. in-line style) when used within other elements as defined by <cite>XHTML 1.1</cite>[<a href="#ref_xhtml11">XHTML1.1</a>]. Normal cascading rules apply.</p>

<h2 typeof='bibo:Chapter' about='#s.4.3' id='s.4.3'>4.3 Forms Usage</h2>

<p>This section is informative.</p>

<p>An HTML form is a dynamic entity when the document is displayed in a browser: data can be entered into text fields, buttons can be pushed, selections made, and options checked. None of this
dynamic activity can be rendered on a printed page. However, a printed page can permanently record a particular state of the form. For example, users might wish to print forms that record products
ordered or payments made.</p>

<p>The following discussion illustrates the activity involved when interacting with and printing forms. Please refer to <a href="#SeqDiag_1">Sequence Diagram 1</a></p>

<p><img id="SeqDiag_1" src="formsUsageModel.jpg" height="404" width="600" alt="Sequence diagram of user, browser, and printer interactions, refer to the following steps" /><br />
<span class="Caption">Sequence Diagram 1. Forms Usage</span></p>

<p>Steps:</p>

<ol>
<li>The User enters a URL into the Browser</li>

<li>The Browser fetches the form from the Server and displays it</li>

<li>The User enters data into the form</li>

<li>The User asks the Browser to print the form</li>

<li>The Browser composes a page with the form and the user data</li>

<li>The Browser sends the newly composed form to the printer</li>

<li>The User selects the Submit button on the form</li>

<li>The Browser sends the user data to the Server</li>
</ol>

<div>
<p>Detailed discussion of Steps:</p>

<ol>
<li>The user interacts with a browser on a mobile device to access a form presented by a server on the network (steps 1 and 2 of <a href="#SeqDiag_1">Sequence Diagram 1</a>). The following fragment
of an XHTML-Print document shows what the server sends to the browser to present to the user. Please note, that the form is blank when first presented to the user. 

<div class="code">&lt;form action="http://example.com/prog/adduser" method="post"&gt;<br />
 &lt;label for="firstname"&gt;First name: &lt;/label&gt;<br />
 &lt;input type="text" id="firstname" /&gt;&lt;br /&gt;<br />
 &lt;label for="lastname"&gt;Last name: &lt;/label&gt;<br />
 &lt;input type="text" id="lastname" /&gt;&lt;br /&gt;<br />
 &lt;label for="email"&gt;email: &lt;/label&gt;<br />
 &lt;input type="text" id="email" size="40" /&gt;&lt;br /&gt;<br />
 &lt;input type="checkbox" name="member" value="IEEE" /&gt; IEEE &lt;br /&gt;<br />
 &lt;input type="checkbox" name="member" value="ACM" /&gt; ACM &lt;br /&gt;<br />
 &lt;input type="submit" value="Send" /&gt; &lt;input type="reset" /&gt;<br />
 &lt;/form&gt;<br />
</div>

<p>Here is an example presentation of the above form as the user would see it:</p>

<form method="post" action="http://example.com/prog/adduser">
<div><label for="firstname1">First name:</label> <input type="text" size="20" id="firstname1" /><br />
 <label for="lastname1">Last name:</label> <input type="text" size="20" id="lastname1" /><br />
 <label for="email1">email:</label> <input type="text" size="20" id="email1" /><br />
 <input type="checkbox" name="member" value="IEEE" /> IEEE<br />
 <input type="checkbox" name="member" value="ACM" /> ACM<br />
 <input type="submit" value="Send" /> <input type="reset" value="Reset" name="Reset" /><br />
</div>
</form>
</li>

<li>The user enters data (step 3 of <a href="#SeqDiag_1">Sequence Diagram 1</a>) into the text fields and checks the IEEE check box so that the form now looks like the following:<br />
 

<form method="post" action="http://example.com/prog/adduser">
<div><label for="firstname">First name:</label> <input type="text" size="20" id="firstname" value="John" /><br />
 <label for="lastname">Last name:</label> <input type="text" size="20" id="lastname" value="Doe" /><br />
 <label for="email">email:</label> <input type="text" size="40" id="email" value="johnd@example.org" /><br />
 <input type="checkbox" checked="checked" name="member" value="IEEE" /> IEEE<br />
 <input type="checkbox" name="member" value="ACM" /> ACM<br />
 <input type="submit" value="Send" /> <input type="reset" value="Reset" name="Reset" /><br />
</div>
</form>
</li>

<li>The user then clicks on the browser's print button (step 4 of <a href="#SeqDiag_1">Sequence Diagram 1</a>), to print the form as it currently appears.</li>

<li>The browser then creates a, possibly new, document (step 5 of <a href="#SeqDiag_1">Sequence Diagram 1</a>) containing the original form and the users data. Note in the XHTML-Print document below,
created by the browser, that the user's data is included either by a value attribute or a checked attribute. 

<div class="code">&lt;form action="http://example.com/prog/adduser" method="post"&gt;<br />
 &lt;label for="firstname"&gt;First name: &lt;/label&gt;<br />
 &lt;input type="text" id="firstname" <span style="background: yellow">value="John"</span>/&gt;&lt;br /&gt;<br />
 &lt;label for="lastname"&gt;Last name: &lt;/label&gt;<br />
 &lt;input type="text" id="lastname" <span style="background: yellow">value="Doe"</span>/&gt;&lt;br /&gt;<br />
 &lt;label for="email"&gt;email: &lt;/label&gt;<br />
 &lt;input type="text" id="email" <span style="background: yellow">value="johnd@example.org"</span> /&gt;&lt;br /&gt;<br />
 &lt;input type="checkbox" name="member" <span style="background: yellow">checked="checked"</span> value="IEEE" /&gt; IEEE &lt;br /&gt;<br />
 &lt;input type="checkbox" name="member" value="ACM" /&gt; ACM &lt;br /&gt;<br />
 &lt;input type="submit" value="Send" /&gt; &lt;input type="reset" /&gt;&lt;br /&gt;<br />
 &lt;/form&gt;</div>
</li>

<li>The browser sends (step 6 of <a href="#SeqDiag_1">Sequence Diagram 1</a>) the document created in step 5 to the printer.</li>

<li>Sometime later the user clicks on the submit form button (step 7 of <a href="#SeqDiag_1">Sequence Diagram 1</a>) and the browser submits the form (step 8 of <a href="#SeqDiag_1">Sequence Diagram
1</a>) using the procedures given in the <cite>HTML 4.01 Specification</cite> ([<a href="#ref_html4">HTML4</a>], <a href="http://www.w3.org/TR/html401/interact/forms.html#h-17.13">Forms

<p>This appendix describes <em title="REQUIRED in RFC 2119 context" class="RFC2119">REQUIRED</em> behaviors for JPEG decoders in XHTML-Print devices. Many of the behaviors described in this document
follow directly from language already present in the relevant JPEG standards, but are repeated here to emphasize their importance.</p>

<h3 typeof='bibo:Chapter' about='#a_jpeg.1.2' id='a_jpeg.1.2'>A.1.2 Objectives</h3>

<p>The decoder behaviors described in this document are intended to minimize implementation complexity, while retaining maximum compatibility with existing JPEG files. In particular, these
recommendations seek to ensure compatibility with both EXIF (Exchangeable Image File Format) and baseline JFIF (JPEG File Interchange Format); i.e., the subset of JFIF files that use only baseline
JPEG processes. Support for JPEG streams using non-baseline processes, such as arithmetic coding or progressive coding, is not mandated for XHTML-Print compliance.</p>

<h2 typeof='bibo:Chapter' about='#a_jpeg.2' id='a_jpeg.2'>A.2 Printer Behaviors</h2>

<p>This section describes behaviors of JPEG decoders for XHTML-Print conformant implementations.</p>

<h3 typeof='bibo:Chapter' about='#a_jpeg.2.1' id='a_jpeg.2.1'>A.2.1 JPEG Processes</h3>

<p>A JPEG decoder for an XHTML-Print printer <em title="SHALL in RFC 2119 context" class="RFC2119">SHALL</em> support all baseline JPEG processes as defined in [<a href="#ref_ccitt">CCITT</a>],
except for 2- and 4-component images. These processes include grayscale and 3-component images, 8-bit/component sample depth, Huffman entropy coding, 444, 422, 411, and 400 subsampling modes, and
sequential (i.e. non-progressive) scan.</p>

<h3 typeof='bibo:Chapter' about='#a_jpeg.2.2' id='a_jpeg.2.2'>A.2.2 Handling of APPx Markers</h3>

<p>Baseline decoders <em title="MAY in RFC 2119 context" class="RFC2119">MAY</em> ignore application-specific markers, such as the JFIF APP0 marker and the EXIF APP1/APP2 markers; rotation fields
within these markers <em title="SHOULD in RFC 2119 context" class="RFC2119">SHOULD</em> be ignored. (Specifically, conforming printers <em title="SHOULD in RFC 2119 context" class="RFC2119">SHOULD
NOT</em> decode the TIFF IFDs embedded in the EXIF APP1 and APP2 markers, as described in Section 2.6.4 of [<a href="#ref_jeida">JEIDA</a>].) This implies images will print in the orientation in
which they are stored, unless style markup indicates otherwise. The image size <em title="SHOULD in RFC 2119 context" class="RFC2119">SHOULD</em> be rendered as specified in the JPEG SOF marker, if
not overridden by style mark-up. A JPEG decoder for a conforming printer <em title="SHALL NOT in RFC 2119 context" class="RFC2119">SHALL NOT</em> fail as a consequence of encountering an unsupported
APPx marker (i.e. all such markers <em title="SHALL in RFC 2119 context" class="RFC2119">SHALL</em> be correctly parsed, even if they are ignored).</p>

<h3 typeof='bibo:Chapter' about='#a_jpeg.2.3' id='a_jpeg.2.3'>A.2.3 Color Management</h3>

<p>This section describes a <em title="RECOMMENDED in RFC 2119 context" class="RFC2119">RECOMMENDED</em> color management approach for XHTML-Print printers.</p>

<h4 typeof='bibo:Chapter' about='#a_jpeg.grayscale' id='a_jpeg.grayscale'>Grayscale Images</h4>

<p>Sample values in a grayscale (single-component) JPEG image <em title="MAY in RFC 2119 context" class="RFC2119">MAY</em> be converted to the sRGB color space by setting</p>

<p style="text-align:center">R<sub>out</sub>= G<sub>out</sub>= B<sub>out</sub>= Gray<sub>in</sub></p>

<p>or by other suitable algorithm specific to the XHTML-Print device.</p>

<h4 typeof='bibo:Chapter' about='#a_jpeg.color' id='a_jpeg.color'>Color Images</h4>

<p>Sample values in 3-component JPEG images <em title="SHALL in RFC 2119 context" class="RFC2119">SHALL</em> be interpreted as YCbCr samples, as would be obtained by applying the matrices described
in ITU BT.601 <strong>[<a href="#ref_bt601">BT601.5</a>]</strong> to sRGB input data.</p>

            XHTML Document Model 
            This module describes the groupings of elements/attributes 
            that make up common content models for XHTML elements. 
            XHTML has following basic content models: 
               xhtml.Inline.mix; character-level elements
               xhtml.Block.mix; block-like elements, e.g., paragraphs and lists
               xhtml.Flow.mix; any block or inline elements 
               xhtml.HeadOpts.mix; Head Elements 
               xhtml.InlinePre.mix; Special class for pre content model 
               xhtml.InlineNoAnchor.mix; Content model for Anchor 
            
            Any groups declared in this module may be used to create 
            element content models, but the above are considered 'global' 
            (insofar as that term applies here). XHTML has the
            following Attribute Groups 
               xhtml.Core.extra.attrib 
               xhtml.I18n.extra.attrib
               xhtml.Common.extra 
            
            The above attribute Groups are considered Global 
        &lt;/xs:documentation&gt;

    Note however that it is not possible to add
    to any head level element without further
    modification. To add RDF metadata to the head
    of a document, modify the structure module.
