RE: RDFa for Firefox

Ben,

You mentioned that the spec only exists for XHTML1.1 now, but this page [1]
lists a spec for HTML 4.01 [2]. And when I look up the DTD sure enough there
is some RDFa stuff in it. Are there any examples of this in use? I ask
because I know of several developers who do not use XHTML and that was there
main deterrent to RDFa. So if it worked and validated they would be likely
to use it.

Thanks,

David Peterson
