But I think we need rules that fit our processes--the XSLT rules fit
with XSLT processing.

I'd wager that no implementer would have a problem with making just
about any attribute into one that supports AVTs, other than those used
in MIPs. This is due to the XForms processing model.

In addition, having AVTs in any attribute that is processed before all
the instances are ready is also a problem, and that would cover:

 * @src (as Joern pointed out);
 * @ev:event and @ev:observer (as Erik hinted at), but not @ev:handler;
 * any XLink construction where the @actuate is on load;
 * XInclude references...

...and so on.

I don't think this going to be too problematic to sort out, and this
only amounts to two rules:

1. No AVTs in MIPs.
2. No AVTs in attributes that are evaluated before the DOM load event.

This is still simple--I agree with you that we need rules--but it also
has the merit of being easy to define in a way that ensures
compatibility with host languages. (At the moment it's
XForms-centric.)

Regards,

Mark
