<!--OddPage--><h2><span class="secno">1. </span>Introduction</h2>
<p>
The profile attribute was introduced in [<a class="bibref" rel="biblioentry" href="#bib-HTML401">HTML401</a>] as a means to specifiy
the location of one or more metadata profiles. The attribute could
contain a space-separated list of tokens or URIs and was primarily
designed to extend the way User Agents processed the HTML document.
User agents could recognize the URI (without actually retrieving the
profile) and perform some activity based on known conventions for that
profile. Applications could also dereference the URI and perform some
activity based on the definitions within the profile.
</p>
<p>
The mechanism to use the contents of the profile attribute
was not defined in [<a class="bibref" rel="biblioentry" href="#bib-HTML401">HTML401</a>]. However, the mechanism on processing
the profile attribute was later described by XMDP, [<a class="bibref" rel="biblioentry" href="#bib-GRDDL">GRDDL</a>], eRDF,
[<a class="bibref" rel="biblioentry" href="#bib-RDFA-CORE">RDFA-CORE</a>], [<a class="bibref" rel="biblioentry" href="#bib-XHTML-RDFA">XHTML-RDFA</a>] and [<a class="bibref" rel="biblioentry" href="#bib-HTML-RDFA">HTML-RDFA</a>]. The mechanism in each
technology defined a set of processing instructions for extracting
semantics from attribute values contained in the HTML document.
</p>
<p>
Specifically, XMDP clarified profile attribute processing, and introduced
a profile document format based on XHTML which authors could produce and
link to using the [<a class="bibref" rel="biblioentry" href="#bib-HTML401">HTML401</a>] profile attribute. GRDDL outlined how one
could use the profile attribute to process the document and
extract metadata. The languages that included RDFa defined how the
profile attribute could be used to pre-declare vocabulary terms and
prefix mappings.
</p>
<p>
While the HTML5 base specification dropped the <code>profile</code>
attribute from the <code>HEAD</code> element, the attribute continues to
be utilized by a number of structured data communities.
</p>
<p>
This document is an extension to HTML5 which achieves the following:
</p>
<ul>
<li>Generalizes the profile attribute to all elements for scoped
indication of vocabularies and metadata processing rules.</li>
<li>Provides a more thorough and rigorous definition of the
profile attribute for languages that include the attribute.</li>
<li>Provides errata for the profile attribute in HTML4 that brings it
in-line with current usage in Microformats, GRDDL and RDFa.</li>

<p class="issue">
Add an example using the profile attribute to
introduce/define/scope a vocabulary and then use in microdata,
microformats, and RDFa markup simultaneously, as a demonstration that they
can be used on the same data in a complementary overlapping fashion. Not
sure of the utility of doing this but demonstrating that they can
be used in the same document or even on the same element may
help both alleviate incompatibility concerns, and how to use shared
vocabularies across multiple syntaxes.

<!--OddPage--><h2><span class="secno">8. </span>HTML 4.01 Errata</h2><p><em>This section is non-normative.</em></p>
<p>
The HTML4 recommendation is inconsistent in its description of the
profile attribute:
</p>
<p>
The DTD specifies <code>%URI;</code>, which just expands to
<code>CDATA</code>. On the other hand, the prose explains that
</p><blockquote>This attribute specifies the location of one or more meta data
profiles, separated by white space. For future extensions, user agents
should consider the value to be a list even though this specification
only considers the first URI to be significant. Profiles are discussed
below in the section on meta data.</blockquote>
<p></p>
<p>
Since the publication of HTML 4.01, a number of meta data profiles have
been defined, and many of them can be used in the same document. While
the profile attribute does not help in discovering which profile applies
to which part of the document, it does allow declaring which profiles are
in use, potentially triggering extended behavior in recipients.
</p>
<p>
This erratum restores consistency in HTML 4.01, explicitly allowing
multiple URIs in a single profile attribute.

<p class="issue">
Do we need to include XMDP interpretations of HTML 4.01 / XHTML 1.0?

profiles. The value of the profile attribute is a whitespace-separated list
of URIs. User agents may use these URIs in two ways:
</blockquote>
<h4 id="section-21---document-type-definition"><a href="http://www.w3.org/TR/html4/sgml/dtd.html">Section 21</a> - Document Type Definition</h4>
<p>
Note: the changes below apply both to the copy of the DTD in the HTML 4.01 spec,
and the actual DTD files.
</p>
<p>
After the definition for <code>URI</code>, insert:
</p>
<pre>
<!ENTITY % URIlist "CDATA"
-- whitespace-separated list of Uniform Resource Identifiers,
see [URI]
-->
</pre>
<p>
Replace the following definition:
</p>
<pre>
<!ATTLIST HEAD
%i18n; -- lang, dir --
profile %URI; #IMPLIED -- named dictionary of meta info --
>
</pre>
<p>
with
</p>
<pre>
<!ATTLIST HEAD
%i18n; -- lang, dir --
profile %URIlist; #IMPLIED -- list of named meta info dictionaries, whitespace separated --
>
</pre>
