I see only one, incidental, problem with your example, once you fix
that it should work:

   <xs:element name="Element1" type="A.B" minOccurs="0"/> in AA

      is not a restriction of 

   <xs:element name="B" type="typeA" minOccurs="0"/> in A

because the element names don't match (and you don't give the type defns).

What error message are you getting, from what processor?
