hi mike, thanks for the quick reply,

I have already has some discussions with henri about support for
validating XHTML 1.0 and HTML 4.01
documents containing ARIA markup and he indicated reluctance at this
stage (understandably).

I have already pinged henri on this particular issue. And as I said
previously, for the most part i think henri has put a good proposal
forward about ARIA integration in HTML5, one which has not been given
the consideration it deserves, as yet. One which serves as a good
basis for discussion on how ARIA integration into other host languages
could proceed.
