XSD Errors

I believe there are a couple of errors in the 1.0 CPP/CPA XSD.
Can they be fixed and a new version released?

Error 1:
 - You are not allowed to specify a Namespace prefix of "xml".
   So xmlns:xml="http://www.w3.org/XML/1998/namespace" should be removed.

Error 2:
 - <attribute name="messageOrderSemantics"
              type="tns:mos.type"
              use="optional"
              value="NotGuaranteed"/>
   This should be:
   <attribute name="messageOrderSemantics"
              type="tns:mos.type"
              use="default"
              value="NotGuaranteed"/>

   Attributes with values specified in the schema must be declared as
   either default or fixed.

Thanks.
