There is still IMHO a bunch of serious issues:
in the case the behaviour is defined as predefined attributes values in an
External DtD, the lik will be detected (or handled properly) only if the Dtd

which one should be used for XPtr and XLink ? Behaviour of linking would be
directly dependant on XSL support ! MS take this as a good opportunity
to get the competition out, and fast !
The schedule for XLink WD publication
Bill Smith called for a co-chair help, no answer so far ...
I'm still hoping we will get to REC for Fall.
