I assume that a document is an instance of element, right? (Please say yes.)

We still need to be XML conforming, so we need a different first character.
John Cowan has convinced me that subsetting Unicode for CharData doesn't
have to be a huge performance issue. Let's not allow chars that XML does
not allow.
We should use the character productions defined in XML. A bit more of a
headache for programmers, but nothing tough.
