XSLT and ABAP Transformation Deep Structure

Question

Hello Everyone,
While I've read the forums and the links of a number of folks doing the same thing. I am stuck in that I cannot figure out how to populate a deep structure via XSLT.  Not sure what is going wrong, but I suspect it is obvious. The simple problem is that my structure is not getting populated. It is blank.  The transformation works in testing STRANS (and in Stylus Studio). 
I cannot figure out what is wrong that makes the t_pexr2002 table blank.  Thanks for any insight.

The simple program is:
TYPES: BEGIN OF ty_head,
          sndprn TYPE string,
          bgmref TYPE string,
          moabetrh TYPE string,
          create_date TYPE string,
          settlement_date TYPE string,
          no_lines TYPE string,
       END OF ty_head.
TYPES: BEGIN OF ty_pricing,
        moabetr TYPE string,
       END OF ty_pricing.
TYPES: BEGIN OF ty_item,
          docname TYPE string,
          docnummr TYPE string,
          pricing TYPE ty_pricing,
        END OF ty_item.
TYPES: BEGIN OF ty_summary,
          status_message TYPE string,
       END OF ty_summary.
TYPES: BEGIN OF ty_mn,
        header_data  TYPE ty_head,
        item_data    TYPE ty_item,
        summary_data TYPE ty_summary,
       END OF ty_mn.
DATA: t_pexr2002 TYPE STANDARD TABLE OF ty_mn.
DATA: xml_doc TYPE REF TO cl_xml_document, xml TYPE string.
CREATE OBJECT xml_doc.
CALL METHOD xml_doc->import_from_file
  EXPORTING
    filename = 'C:\temp\2640273.xml'.
CALL METHOD xml_doc->render_2_string
  EXPORTING
    pretty_print = 'X'
  IMPORTING
    stream       = xml.
CALL TRANSFORMATION zusl_pexr2002_v1
SOURCE XML xml
RESULT output = t_pexr2002.

Here is my XSLT:
Here is the transformation: Also pretty simple...
<xsl:transform xmlns:xsl="http://www.w3.org/1999/XSL/Transform" ... >
  <xsl:strip-space elements="*"/>
  <xsl:template match="/PEXR2002/IDOC">
    <asx:abap xmlns:asx="http://www.sap.com/abapxml" version="1.0">
      <asx:values>
        <OUTPUT>
            <HEADER_DATA>
              <SNDPRN>
                <xsl:value-of select="EDI_DC40/SNDPRN"/>
              </SNDPRN>
              <BGMREF>
                <xsl:value-of select="E1IDKU1/BGMREF"/>
              </BGMREF>
              <MOABETRH>
                <xsl:value-of select="E1IDKU5/MOABETR"/>
              </MOABETRH>
              <CREATE_DATE>
                <xsl:value-of select="EDI_DC40/CREDAT"/>
              </CREATE_DATE>
              <SETTLEMENT_DATE>
                <xsl:value-of select="E1EDK03/DATUM"/>
              </SETTLEMENT_DATE>
              <NO_LINES>
                <xsl:value-of select="count(E1IDPU1)"/>
              </NO_LINES>
            </HEADER_DATA>
            <ITEM_DATA>
              <xsl:for-each select="E1IDPU1">
                <DOCNAME>
                  <xsl:value-of select="DOCNAME"/>
                </DOCNAME>
                <DOCNUMMR>
                  <xsl:value-of select="DOCNUMMR"/>
                </DOCNUMMR>
                <PRICING_DATA>
                  <xsl:for-each select="E1IDPU5[MOAQUAL = '006']">
                    <MOABETR>
                      <xsl:value-of select="MOABETR"/>
                    </MOABETR>
                  </xsl:for-each>
                </PRICING_DATA>
              </xsl:for-each>
            </ITEM_DATA>
            <SUMMARY_DATA>

                </STATUS_MESSAGE>
              </xsl:for-each>
            </SUMMARY_DATA>
        </OUTPUT>
      </asx:values>
    </asx:abap>
  </xsl:template>
</xsl:transform>
