> what aspect of <msIdentifier> is not handled?

I phrased that poorly. Of course <msIdentifier> *can* be handled, but
not as a single class, no matter how clever we make classes, they're
not content models.

The content model of <msIdentifier> has structure:

  element msIdentifier {
         | msName
        ( altIdentifier | msName )*

Note that in the inside set there <settlement> and <repository> are
not optional, but everything else is.

Ah, now I understand. This doesn't bother me because it is no
different than what happens when the user deletes a required child
element when the required child element is in the same module as the
parent. (It doesn't mean I don't think we should try to do something
nicer, it just means it's orthogonal to module dependency.)

I'm not sure how you're defining "behaviour" here. Is something
like "if a module depended on by an explicitly loaded module cannot
be found and loaded, an error condition should be raised and no
output (schema, reference doc, etc.) should be generated"

Well, yes, it's module dependency merely documented instead of properly

Right, which is why I'm not so fond of it, and far prefer your
suggested 3.5 solution.

I'm imagining a little more forceful than that. I'm imagining "when
you buy this you get that for free" ... if you don't want 'that', you
have to explicitly say so.

If you say so. Sometimes makes my head spin thinking of the stuff you
do. Although it's far worse today, as my head was already spinning
from jet-lag. :-)
