def:WhereClause with reference to different domain is not supported yet.

For example, in the case below:

 <def:WhereClauseDef OID="WC.VS.VSTESTCD.HEIGHT.[DM].COUNTRY.CNMETRIC" def:CommentOID="COM.SUBJECTDATA-JOIN-DM">
        <RangeCheck SoftHard="Soft" def:ItemOID="IT.VS.VSTESTCD" Comparator="EQ">
          <CheckValue>HEIGHT</CheckValue>
        </RangeCheck>
        <RangeCheck SoftHard="Soft" def:ItemOID="IT.DM.COUNTRY" Comparator="EQ">
          <CheckValue>USA</CheckValue>
        </RangeCheck>
      </def:WhereClauseDef>

This whereclause is applied to VSTESTCD variable, but the second RangeCheck refers to COUNTRY variable in DM domain. In that case, currently Define2Validate fails to find variable name in DM domain, and the generated rule will have invalid syntax.
