Hi Francis,

thanks for your patient explanation. I understand the reuse of elements  
via a group and all the XML stuff but we have a situation here that the  
schema doesn't cover sufficiently: potential restrictions within the  
elements that use the element group that are not handled by the schema.  
For a similar situation I refer to the use of the element group in  
21.2.2.47 dLbl. This actually uses two nested element groups. But, as both  
are sequences the ordering is clear and can be validated.

<xsd:group name="Group_DLbl">
     <xsd:sequence>
        <xsd:element name="layout" type="CT_Layout" minOccurs="0"  
maxOccurs="1"/>
        <xsd:element name="tx" type="CT_Tx" minOccurs="0" maxOccurs="1"/>
        <xsd:group ref="EG_DLblShared" minOccurs="1" maxOccurs="1"/>
     </xsd:sequence>
</xsd:group>

If sequences are used here then why not in colours?

I suggest that this be referred back to Microsoft for clarification.
