Should be the restricted, otherwise what's the point?

That's a bug in the spec., in my opinion, with hindsight.  The
spec. says the enumeration values must be valid (and as a consequence,
normalized with respect to) the base type defn, not the type defn
itself.  It's simpler that way, but at best confusing (as in your
example) and at worst bizarre:

<simpleType>
 <restriction base="string">
  <maxLength value="1"/>
  <enumeration value="xx"/>
 </restriction>
</simpleType>

is a legal, unsatisfiable, type definition, per the spec.

I _think_ I'd prefer to see the checking and normalization done
against the type defn itself.

Yes, but my locally patched version also fails.
