this one is imprecise as worded. i'll leave it to others to refine it... :)

a method to do this with pi's has been demonstrated.
it should also be possible to do this with attributes' default declarations.
in that case, similar scoping rules could be inferred from the content models.
so long as there were no contradictions implied, this would work for your 50M files.

see above. given a default declaration on a "root" element, the remainder
could be inferred.

no comment.

i don't see why this is necessary. wouldn't your 50M case would alread have dtd's?
