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>
