Ok, it does sound like this could be a substitution group.

<xs:element name="bindingElement" type="bindingType"/>

<xs:complexType name="classType">
   <xs:sequence>
     <xs:element ref="bindingElement"/>
   </xs:sequence>
</xs:complexType>

// in the sales namespace
<xs:element name="Bar" substitutionGroup="webbeans:bindingElement"/>

// in the acme namespace
<xs:element name="Foo" type="classType"/>
