I see your point, but I agree with Daniel. The XLink Recommendation
can describe how an XLink processor must behave if processing an XLink
element. Another specification can describe how to behave if
processing an element in its vocabulary.

In the case where an element occurs in both vocabularies and these two
actions are not the same, it's likely that the application will have
to intervene. Perhaps give the user a choice, or a warning?

The XLink specification cannot proscribe HTML behavior on an XHTML "a"
element and reasonably expect to get public support. I suppose it
could defer to another vocabulary in which it appears, but in that
case an XLink processor unaware of the other vocabulary cannot

A user that produces

  <a href="x" xlink:href="y" ...>

has probably made an error, but only he knows for sure.
