The Schema for Schemas rules this out:

 <xs:complexType name="localElement">
   <xs:restriction base="xs:element">
    . . .
    <xs:attribute name="substitutionGroup" use="prohibited"/>

This only applies to the XML representation layer, of course.

It's a bug that there's no clause in "Schema Component Constraint:
Element Declaration Properties Correct" ruling this out for components 
as well.
