Right.

They are two *completely* different things. In a KWord document, if you have
5 framesets, each of them has a KoTextDocument.
A KoTextDocument (the name comes from QTextDocument in QRichText)
is a list of paragraphs (nothing else).

Right, like in all koffice documents.

Depends for which features. Please elaborate.

Not from a base KoTextDocument (since that's used by kpresenter too ;)
but a KWTextDocument knows about its host frameset, which knows about
its host KWDocument. I'm not sure you need that though. Well, that really 
depends what you're trying to do ;-)
