I had an action[1] to document the @id/@about ambiguity issue and open it up for discussion:
http://rdfa.info/wiki/rdfa-in-html-issues#Mixing_id_and_about_on_the_same_element We need to determine if creating markup like this is an acceptable practice: <p id="foo" about="#foo">Some text</p> The argument is that the document containing the markup above contains two semantically different URLs to the same location, thus creating some semantic ambiguity.
