A conformant XML processor should simply throw a well-formedness exception. A better example, which, although invalid, should be accepted but interpreted differently under HTML and XML parsers is: <div about=""> <table about="#me"> <p property="dc:title">Hello World</p> </table> </div> An HTML parser will lift the <p> element out of the table and place it as a child of the <div> (IIRC it will be inserted prior to the <table>) because <p> is not an allowed child of <table>. So in HTML+RDFa will get: <> dc:title "Hello World" . # and no triples about <#me> And in XHTML+RDFa: <#me> dc:title "Hello World" . # and no triples about <> Yay, fun. :-) What other fun ones can I think of...? <html about="#foo"> <h1 property="dc:title">Hello World</h1> <p property="dc:description">A global greeting for all.</p> </html> Anyone want to guess the subject URI for the two triples when processed as HTML? Hint: it ain't <#foo>. -- Toby A Inkster <mailto:mail@tobyinkster.co.uk> <http://tobyinkster.co.uk>
