RE: identity constraint with "xsd:any" and self-embedded element

Thanks for your reply, I feel it quite strange because if I change the
instance file to valid version (see below), the XERCES schema validator
still reports error. Maybe I could try other version validator. 

<?xml version="1.0"?>

<myNS:root xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:myNS="myNS.tempuri.org">
   <myNS:t myNS:col="3">    
      <myNS:row>1</myNS:row>
      <myNS:row>2</myNS:row>
      <myNS:t myNS:col="2">
          <myNS:row>3</myNS:row>
          <myNS:row>4</myNS:row>
      </myNS:t>
   </myNS:t>
</myNS:root>

Best Regards,
Yongnian

Your constraint as written says "all the rows which share a 't'
ancestor must have unique content", and your instance evidently
violates that.  If what you mean to say is "all the rows which share a
't' _parent_ must have unique content", then just write


      <xsd:key id="foo1" name="tableu1">

          <xsd:selector xpath="myNS:row"/>

          <xsd:field xpath="."/>

      </xsd:key>
