So, just as a stylesheet could be designed for a particular DTD,
so too could a Bindings document. Or a Bindings document might
apply to a "library" of element/attribute definitions.

I think that you are also underscoring a need for delegation.

I'm not yet sure whether I agree with the first-encountered rule.
We need to examine the cost of not allowing bindings to be cumulative.

That would be one way to look at it. Another way to keep it
fairly light-weight is to allow that a set of Bindings might
be contained in the same document. Thus, we would maintain
a link mechanism is all cases, but allow for the equivalent
of a fragment identifier (#) to say that te Binding is located
in the self-same document.
