no, EMBED is _not_ an include facility. External text entities are.

Right. That's why XML has the "internal subset. You put the any _per-document_
declarations there, (inside the square brackets of the doctype) and they
augment the DTD, without removing it.

No; Yes; Yes.

for example, you might have:

<!doctype RML SYSTEM "some:URL/goes/here"
<!ENTITY boilerplate SYSTEM "http://Joes-server.isp.com/disclaimer">

.... later on in your document ...

The entity reference to "boilerplate" will include the whole disclaimer without
having to change the DTD, or fill it with weird private information. Is this
good enough?
