Hi John,

I think you are on to something. :)

Just sticking with the 'bind' module (as currently named), I'd suggest
that perhaps the key part is the dependency-graph; everything else
concerns the graph's reflection via events to the UI, and associated
CSS properties. So we might consider naming this module something more
to do with that, rather than simply 'bind', and then throwing in
everything that makes it work.

Which reminds me...a few years ago I did a paper at the W3C web apps
workshop on how a set of standardised modules might relate to each
other [1], and I called what amounts to the bind module a 'dynamic
infoset' module.

Augmenting an infoset with dynamic properties is the _purpose_ of the
dependency-graph, so this might be a better moniker. I think such a
name also reflects some of the original design goals of XForms 'bind',
that I believe existed in the early work by yourself, Roland, Raman,
and others.

Regards,

Mark
