You can use binds at your leisure, there are just no binds that need
to target anything in the template, and no duplication of binds. Your
initial point was that there would be a mess, a duplication of
binds. I say no, I don't see why that would be. Your binds, if you
want any, are still against your main instance, like in your XForms
1.0 first edition scenario.

The bind identifies some nodes, typically elements, and then applies
some properties to those nodes. If nodes are there, great, if nodes
appear, they will be included when the binds are reevaluated, and if
nodes disappear, they will be removed when those are reevaluated. I
think it works as you would think it should.
