Hello,

I'm reading Steven Pembertons talk:

blockquote cite="http://www.w3.org/2005/Talks/05-steven-xtech/"

   We can now say that <meta> and <rel> define RDF triples:

     * 'about' is the subject,
     * 'property' and 'rel' are the predicate,
     * for <meta> the content is a string or XML literal object,
     * for <link> 'href' gives the object.

/blockquote

I like the idea of adding precise semantics to XHTML. Maybe Steven 
simplified things, but I don't think this has anything to do with meta 
and link, because it works with any element. I think this
should be:

   We can now say that 'property' and 'rel' define RDF triples:

     * 'about' is the subject,
     * 'property' and 'rel' are the predicate,
     * for 'property' the content is:
       - a string when there is a 'content' attribute,
       - an XML literal object otherwise,
     * for 'rel' 'href' gives the object.

(It took me a while to realize the difference between 'property' and
'rel', but I think this is it.)

Also:

blockquote cite="http://www.w3.org/2005/Talks/05-steven-xtech/"

   Now we can just say that

   <p id="p123" title="whatever">

   is equivalent to:

   <p id="p123">
      <meta about="#p123" property="title">whatever</meta>

/blockquote

If this is true then it should be stated somewhere that content of the 
meta element must not be rendered by the user agent.

greetings,
