&ltrulebase metaversion="1.0">
  &ltname&gtCatalog Validations</name>
  &ltdescription&gtCatalog Validations</description>
  &ltexecution_directive first_pass="required"/>
  &ltconstraint>
    &ltname&gtTest1</name>
    &ltdescription&gtTest1</description>
    &ltaction>
      &ltassign>
        &ltvar&gtUOM</var>
        &ltop func="trim">
          &ltvar&gtUOM</var>
        </op>
      </assign>
    </action>
  </constraint>
  &ltconstraint>
    &ltname&gtTest</name>
    &ltdescription&gtTest</description>
    &ltusefor>
      &ltvar&gtUOM</var>
    </usefor>
    &ltaction>
      &ltcheck>
        &ltexplanation&gtThis has to be unique in the master catalog</explanation>
        &ltduplicate>
          &ltvar&gtUOM</var>
        </duplicate>
      </check>
    </action>
  </constraint>
</rulebase>
