This proposal allows data-oriented stuff to be put into custom 
attributes. So assuming we'd associated URIs with prefixes somehow, I 
think we could write this sort of thing and it would at least be legal 
HTML5:

<ul>
<li data-about="/user/markb/photo/23456"> <a href="/user/markb/photo/23456">
<img src="/user/markb/photo/23456_thumbnail" />
</a>
<span data-property="dc:title">Sunset in Nice</span> taken by photographer
<a data-property="dc:creator" href="/user/markb">Mark Birbeck</a>, 
licensed under a
<a rel="cc:license" href="http://creativecommons.org/licenses/by-nc/3.0/">
Creative Commons Non-Commercial License </a>.</li>
</ul>

Apparently SVG can be embedded now. But SVG allows RDF/XML inside its 
<meta> element; not clear how HTML5 will deal with something like this:

'xmlns “attributes” have no effect, but will be allowed so that tool 
output is by default compatible. They might even end up in the correct 
namespace, http://www.w3.org/2000/xmlns/. '

See http://www.w3.org/TR/SVG/metadata.html

Where does this leave image accessibility?

<li>
<svg width="4in" height="3in" version="1.1" xmlns = 
'http://www.w3.org/2000/svg'>
<metadata>
<rdf:RDF
xmlns:rdf = "http://www.w3.org/1999/02/22-rdf-syntax-ns#"
xmlns:rdfs = "http://www.w3.org/2000/01/rdf-schema#"
xmlns:foaf = "http://xmlns.com/foaf/0.1/"
xmlns:dc = "http://purl.org/dc/elements/1.1/" >
<rdf:Description about="http://example.org/myfoo"
dc:title="MyFoo Financial Report"
dc:date="2000-04-11"
dc:format="image/svg+xml"
dc:language="en">
<dc:creator><foaf:Person><foaf:openid 
rdf:resource="http://danbri.org/"/></foaf:Person></dc:creator>
</rdf:Description>
</rdf:RDF>
</metadata>
</svg>
</li>

Interesting developments, both of them...

cheers

Dan
