Why SAX needs namespace support

I can, off the top of my head, think of lots of times where mixing elements
from other dtds would make sense. A few that sprang to mind:
	Any kind of fiction (include a poem, recipe, formula etc).
	News articles (ditto above).
	Linguistics (include a fragment of text in a foreign language).

I know this isn't quite what Mr. Prescod had in mind (I think), but it
seems like a useful thing to be able to do. Why, if you include a
"poem.dtd" in another kind of document, couldn't you process the fragment
of the document (the poem or poems) in the "process space" (namespace?) of
that dtd or stylesheet or whatever?
