Mihaela Mihaljevic 711a50b8ea feat(schema): reject ur-type widening in element restriction 
Extend NameAndTypeOK: restricting a concrete-typed element to an ur-type
(xs:anyType / xs:anySimpleType / xs:anyAtomicType) is widening, hence an invalid
restriction. The element-vs-element check now rejects it before the atomic
derivation check.

The ur-type is recognised by a type reference whose key is anyType /
anySimpleType / anyAtomicType AND which is absent from the named-type table, so
a user type that merely shares the local name (in another namespace) is not
mistaken for the ur-type. The reverse (an ur-type base narrowed by the
restriction) stays valid.

XSTS: invalid schemas accepted 620 to 616, valid schemas rejected held at 72,
instance buckets unchanged.
