I am jumping in late (just saw the thread), you can use a complexType 
to get inheritance. For example:

<xs:complexType name="BaseNode">
   <xs:sequence>
     <xs:group ref="name:core.elems"/>
   </xs:sequence>
   <xs:attributeGroup ref="name:core.attrs"/>
</xs:complexType>

<xs:complexType name="ParentNode">
     <xs:complexContent>
       <xs:extension base="name:BaseNode">
         <xs:sequence>
           <xs:element ref="name:ChildNode"/>
         </xs:sequence>
       </xs:extension>
     </xs:complexContent>
   </xs:complexType>

<xs:complexType name="ChildNode">
     <xs:complexContent>
       <xs:extension base="name:BaseNode">
         <xs:sequence>
           <xs:element ref="name:SomethingElse"/>
         </xs:sequence>
       </xs:extension>
     </xs:complexContent>
   </xs:complexType>

Is that what you are talking about?

best,
-Rob
