Correct me if I am wrong, but can we have the XSD capture this constraint explicitly ? For instance, <xs:element name="operation" type="wsdl:BindingOperationType"> <xs:unique name="messageLabel"> <xs:selector xpath="(wsdl:input|wsdl:output:wsdl:infault|wsdl:outfault)"> <xs:field xpath="@messageLabel"> </xs:selectpr> </xs:unique> </xs:element> 14583 2 jonathan 2007-03-29 17:02:42 +0000 Per http://lists.w3.org/Archives/Public/www-ws-desc/2007Mar/att-0083/20070329-ws-desc-minutes.html#item04 closed with no action. The specification of a uniqueness constraint is incompatible with the optionality of the attribute.
