This is already on the "potential erratum" list for the Namespaces
spec, and will be clarified one way or the other.

I don't know how it will turn out, but I strongly recommmend that you
avoid declaring the xml prefix, and that tools at least warn about it,
since not declaring it will certainly continue to be legal!
