<div class="expand_description">
<p>Since XML 1.0, the ability of processors to identify an XML
element by an explicit identifier ("IDness") has depended upon
validation. Both DTDs and [XML Schema] have
mechanisms to identify the structures containing unique
identifiers. But neither XML Schema nor DTDs are required by all
processors. A common processor type does not perform validation,
nor fetch external resources for the purpose of acertaining whether
the document contains unique identifiers.</p>
<p>This document sets out the requirements for a mechanism for
determining "IDness" applicable to all classes of XML
processors.</p>
