IBM Rational (RQM): Loop over custom field

In the IBM Rational connector, when specifying raw XML you can embed multi-select custom fields, and loop over them to repeat XML.

In the example xml below we have a multi select field called 'multi' which is overlaid on the model.

  <ns4:title>{{TestPathAttributes.TestName}}</ns4:title>
  <ns4:description>{{TestPathAttributes.TestSummaryListHTML}}</ns4:description>
$ foreach Item in {{TestModelVersionAttributes.Custom}}[multi] $
                <ns2:category term="Family" value="{{Item}}" />
$ endforeach $
</testcase>

When the XML is resolved the category tag is repeated per the value of the multi-select field.
