XML may be formally defined, but that doesn't mean that
XML documents must be.  English can be formally defined
(more or less; our understanding of English is incomplete),
but a document in English exists iff someone has
fixed it in a concrete medium.

Not the definition of XML, only the defn. of
"document".

m-w.com gives the following definitions:

	An original or official paper relied on as the basis,
	proof, or support of something.

	Something (such as a photograph or a recording) that serves
	as evidence or proof.

	A writing conveying information.

	A material substance (as a coin or stone) having on it a
	representation of thoughts by means of some conventional
	mark or symbol.

All of which specify a substrate, not a mere abstraction.
