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). >"It also flags issues based on a set of > rules, defined by Henri, on what constitutes conformant HTML5+ARIA > (for example role="document" is not allowed)" and understand the > concern you're expressing. 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. regards stevef 2008/9/30 Michael(tm) Smith <mike@w3.org>: > Hi Steven, > > I would think it'd be doable to add support in validator.nu > experimental support for validating XHTML 1.0 and HTML 4.01 > documents containing ARIA markup.
