??? Is this right?  I thought anyType can function as a complex type _only_,
not a simpleType.   The rest of the specs seems to imply that the definition
might be "The ur-type definition, whose complexType name is anyType and whose
simpleType name is anySimpleType, has the unique characteristic .... ".  Or am
I not fully understanding the functionality of anyType and anySimpleType.
