There's a comment in the non-normative section 3.14.1 saying it
shouldn't be named as a base type in a user definition.

This is certainly wrong on one count -- it rules out defining a user-named
synonym for anySimpleType, which should be OK.

It's probably wrong on another count -- both whiteSpace and pattern
facets make sense as restrictions on aST, and the sForS actually gives 
whiteSpace facet values in all its pseudo-definitions of the builtin
in primitives.

So I think the comment should be changed to point out instead that only
those facets make sense, and a normative prohibition of any others
should be added to part 2.
