Hi Wong,

You need do something like:

<xs:element name="myelement">
 <xs:complexType>
  <xs:simpleContent>
   <xs:extension base="xs:string">
    <xs:attribute name="myattrib1" type="xs:string" />
    <xs:attribute name="myattrib2" type="xs:string" />
   </xs:extension>
  </xs:simpleContent>
 </xs:complexType>
</xs:element>

I've just completed a beginners primer on XSD that tries to describe Schema 
in the sort of way you asked your question (i.e. if you want X in your XML, 
do Y in your Schema).  It may well be 'yet another guide', it certainly 
doesn't cover all of XSD, and you've probably moved beyond its target 
audience, but if you find you have any comments on it I'd be delighted to 
know.

Cheers,

Pete.
