Thanks Chee-Kai

Is there any way to then specify what 'is' being used for validation
when substitutionGroups are involved?
My fear is that there isn't so there is no way to say what *isn't* valid.

The presence of substitutionGroups can also create a sense
of "the element is not the type which it's present manifest
type suggests" -- in other words, what type you see that's
associated with an element at present may not be what is being
used for validation.  The situation would be worsened if the 
actual substitution definitions come in from another <include>d
file stored physically elsewhere, and might also introduce
possible authenthicity issues (eg. allowing validation using 
bogus subsituted groups when invalid codes exist in instances).
