Get a built-in simple type of the given name
REVISIT: its still not decided within the Schema WG how to define the
         ur-types and if all simple types should be derived from a
         complex type, so as of now we ignore the fact that anySimpleType
         is derived from anyType, and pass 'null' as the base of
         anySimpleType. It needs to be changed as per the decision taken.
Params:
name –  the name of the datatype
Returns:
     the datatype validator of the given name/**
