That's one complication.

Only that the Namespaces REC speaks specifically of the namespace
well-formedness of "documents" and an external parsed entity isn't a
document.

Michael Kay proposed, basically, a definition that said if you added a
wrapper around the content of the external parsed entity, the result
was namespace well-formed. I asked how that was different from saying
that each top-level element was namespace well-formed.

Then I proposed that the Core WG might have an opinion. :-)
