</h2><p><a href="#XSL">[XSL 1.0]</a> defines the features and syntax for the
Extensible Stylesheet Language (XSL), a language for expressing stylesheets.
It includes an XML vocabulary for specifying formatting semantics. An XSL
stylesheet specifies the presentation of a class of XML documents by describing
how an instance of the class is transformed into an XML document that uses
the formatting vocabulary.</p><p>Since becoming a Recommendation on 15 October
2001, XSL 1.0 has enjoyed widespread support. However, the user community
has expressed requirements that have encouraged various implementations to
provide extensions to the language. These extensions--especially those implemented
by more than one implementation--are clear candidates for standardization
so as to maximize interoperability.</p><p>The XSL Working Group has surveyed
and analyzed various existing extensions, user requirements, and features
intentionally cut from XSL 1.0 due to lack of time. Using the results of this
research, the Working Group is developing an XSL 1.1 version that incorporates
current errata and includes a subset of relatively simple and upward compatible
additions to XSL.</p></div><div class="div1"><h2><a id="requirements" name="requirements"></a>2
Requirements</h2><p>Since there are already various non-interoperable extensions
for many of these features, it is crucial that XSL 1.1 be developed in a timely
manner. It is important that added XSL 1.1 features correspond to things that
implementors have implemented or things that can be implemented in a reasonable
time frame.</p><p>After research, requirements gathering, and discussions
with vendors and within the working group, we developed the following set
of potential requirements for added features to XSL 1.1:</p><ol>
<li>Change bars</li>
<li>Index improvements, especially merging page numbers</li>
<li>Conditional graphic scaling, e.g., "scale-down-to-fit"</li>
<li>Table of contents windows (aka bookmarks)</li>
<li>Table markers that allow dynamically determined text to be put into table
headers or footers</li>
<li>Support for a value of "only" for the page-position property</li>
<li>Support for a page-number-citation-last formatting object (retrieving
the last page number of a section or document)</li>
<li>Support for "flowmaps" and other region/float extensions</li>
</ol><p>The working group plans to develop detailed descriptions of each of
these features and may decide to omit something from XSL 1.1 if it does not
appear to be addressable within a reasonable time frame.</p><p>The working
group is also maintaining a list of other potential requirements to XSL <a
href="#post-xsl11">[Post-XSL 1.1]</a> that have already been deemed to be
beyond the scope of XSL 1.1.</p></div></div><div class="back"><h1 id="id-required-by-pubrules-5">
