That's a correct prose description, but that's not the same thing as
determining that the attribute is ID-typed.
<foo id="bar" fakeId="bar"/>
Your test will return true for both attributes above. I can be sure that one
of them is ID-typed, but I can't be sure which one, or even if both of them
are (because input may be invalid).

That assumes that the XSLT processor always has control over the serializer
(and hence its being an optional feature). I can't make that assumption. So,
I'll probably just use an intermediate representation a la a my:idatts
attribute to denote which attributes are ID-typed. So postulate that I've
got the ID-generation problem solved.
But I have no way of figuring out which attributes are ID-typed in the first
place!
