Do you mean something like

  <xs:complexType name="tBase">
  </xs:complexType>

  <xs:complexType name=tBaseWithSetAttributes>
   <xs:complexContent>
    <xs:extension base="tBase">
     <xs:attribute name="type"
      type="tns:HibernateCollectionElements" fixed="Set"/>
     <xs:attribute name="s1" type="xs:string"/>
     <xs:attribute name="s2" type="xs:string"/>
     <xs:attribute name="s3" type="xs:string"/>
    </xs:extension>
   </xs:complexContent>
  </xs:complexType>

  <xs:complexType name=tBaseWithBagAttributes>
   <xs:complexContent>
    <xs:extension base="tBase">
     <xs:attribute name="type"
      type="tns:HibernateCollectionElements" fixed="Bag"/>
     <xs:attribute name="h1" type="xs:string"/>
     <xs:attribute name="h2" type="xs:string"/>
    </xs:extension>
   </xs:complexContent>
  </xs:complexType>
