I've been observing the development of DSDL, and I have good hope that
DIS 19757 Part 2, a.k.a. RELAX NG, would become an International Standard
within the time frame of XHTML2 (that's part of the reasons why I'm
investigating the possibility of using RELAX NG for XHTML2, after all).

But I'm not so optimistic to expect that the whole DSDL work can be done 
within the time frame of XHTML2.  DSDL is a large and ambitious project,
it was originally Part 0 through 7 but now it's Part 0 through 9, I believe
at some point there was one more Part.  It is not clear at the moment how
anything other than Part 2 would end up.  At least I don't expect we can
rely on Part 9 any time soon.

I have nothing against DSDL's approach and I believe the HTML WG's position
won't contradict with DSDL's approach, but we have to work out a reasonable
solution within the constraint of currently-available technologies.

There might be a slight chance that the development of XHTML 2.0 would be
significantly delayed and DSDL would be done, but certainly I don't want
to count on that possibility ...
