Re: [XBL] Abstract

Hi Ian,
XForms has two major components, things that have to do with the data model
and things that have to do with UI controls. The data model includes a
(fairly simple) data dependency engine and a event-driven processing model
with a number of different events defined. These things require a dedicated
engine. XBL doesn't help with these features.

But XBL definitely makes sense for UI controls. In fact, last I heard, the
XForms extension to Mozilla leverages XBL heavily for the implementation of
its UI controls. (Steve might know more about this than me.)

It's not a big deal with regard to the spec one way or the other, but I
think Steve's feedback is on target.

I'm not sure it really is overstating it. What couldn't be done with XBL
as far as implementing XForms goes?
