 /**

  * This XML Filter is used to transform the <member> section generated in GroupNamespaceURIMemberTransformationFilterPOC.

  * such that the transformation from the pre-filtered pre-1.0.3 XML document looks like this:

  * 

  *   -- Example from GroupXmlImportTest.xml as filtered by GroupNamespaceURIMemberTransformationFilterPOC -- 

  *   <members>

  *       <memberId>ewestfal</memberId>

  *       <memberId>rkirkend</memberId>

  *       <memberId>2015</memberId>

  *   </members>

  *   

  *   -- Resulting transformation --

  *   <members>

  *       <member>

  *           <memberId>ewestfal</memberId>

  *                    <memberTypeCode>P</memberTypeCode>

  *       </member>

  *       <member>

  *           <memberId>rkirkend</memberId>

  *                    <memberTypeCode>P</memberTypeCode>

  *            </member>

  *           <member>

  *                   <memberId>2015</memberId>

  *                   <memberTypeCode>P</memberTypeCode>

  *      </member>

  *   </members>

  * 

  * Note 1: This filter assumes that <memberTypeCode> should be defaulted to "P" for all members. 

  *         

  * Note 2: As is the case with GroupNamespaceURIMemberTransformationFilterPOC, this filter has methods for transforming 

  *         the attributes of elements, but all they do is return "new AttributesImpl()". If it is necessary to transform 

  *         attributes of pre-1.0.3 elements, we can build those methods out.
