Yes. That is the obvious error I mean. I might be mistaken, but to me
this makes the document not well-formed (and thus automatically invalid
since well-formedness is a prerequisit...).

True. I never got that far, since my parser barfed already on the
unmatched </a> tag.

Interesting read. Since the document is supposed to be XHTML, I guess
the quotes must be mandatory anyway.

Thanks for the insights,
