could you then provide us an instance illustration?

Sure - here it is. This is an agency's schema (agency 1) that includes
the vocabulary of agency 2. The element "StateCode" is used in 2
different contexts for each vocabulary:

<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema"
	    xmlns:a1="http://www.agency1.gov" 
	    xmlns:a2="http://www.agency2.gov" 
            targetNamespace="http://www.agency1.gov"
            elementFormDefault="qualified"> 

...[import of agency 2's schema goes here]...

   <xsd:element name="Address"> 
          <xsd:complexType> 
              <xsd:sequence> 
                  <xsd:element ref="a1:Street"/> 
                  <xsd:element ref="a1:City"/>  
                  <xsd:element ref="a1:StateCode"/>  	 
                  <xsd:element ref="a1:ZipCode"/>  
                  <xsd:element ref="a1:Country"/>   
            </xsd:sequence> 
        </xsd:complexType> 
    </xsd:element> 

   <xsd:element name="ElementInformation"> 
          <xsd:complexType> 
              <xsd:sequence> 
                  <xsd:element ref="a2:Name"/> 
                  <xsd:element ref="a2:StateCode"/>  	 
			...[more stuff here]...
            </xsd:sequence> 
        </xsd:complexType> 
    </xsd:element>
