[xsl] Dynamic attribute name in predicate - 2nd try

David et al., thanks for prior response.  I thought brevity had a higher
priority than completeness in my prior post.  Let me try again.
****data sample*******
<dsQueryResponse>
    <Rows>
      <Row GroupAssigned="CRA"   Source="Other" Status="TBD" FW="" FM="" FQ=""
FY=""  />
      <Row GroupAssigned="HR"    Source="Other" Status="Accept" FW="9"
FM="JUN" FQ="1" FY="10"  />
      <Row GroupAssigned="CRA"   Source="EC_MailBox" Status="Accept" FW="9"
FM="JUN" FQ="1" FY="10"  />
      <Row GroupAssigned="CRA"   Source="EC_MailBox" Status="TBD" FW="9"
FM="JUN" FQ="1" FY="10"  />
      <Row GroupAssigned="HR"    Source="EC_MailBox" Status="Accept" FW="9"
FM="JUN" FQ="1" FY="10"  />
      <Row GroupAssigned="CRA"   Source="Other" Status="VettedOut"  FW="9"
FM="JUN" FQ="1" FY="10" />
      <Row GroupAssigned="CRA"   Source="EC_MailBox" Status="Accept" FW="12"
FM="JUN" FQ="1" FY="10"  />
      <Row GroupAssigned="HR"    Source="Other" Status="Accept"  FW="9"
FM="JUN" FQ="1" FY="10"  />
      <Row GroupAssigned="CRA"   Source="Other" Status="Accept"  FW="9"
FM="JUN" FQ="1" FY="10"  />
      <Row GroupAssigned="CRA"   Source="EC_MailBox" Status="VettedOut"  
FW="9" FM="JUN" FQ="1" FY="10" />
      <Row GroupAssigned="CRA"   Source="AltertLine" Status="Accept"    
FW="9" FM="JUN" FQ="1" FY="10"  />
      <Row GroupAssigned="HR"    Source="AltertLine" Status="VettedOut" FW="9"
FM="JUN" FQ="1" FY="10"   />
      <Row GroupAssigned="Legal" Source="EC_MailBox" Status="VettedOut" 
FW="9" FM="JUN" FQ="1" FY="10"  />
      <Row GroupAssigned="Legal" Source="Other" Status="Accept"  FW="9"
FM="JUN" FQ="1" FY="10" />
    </Rows>
<dsQueryResponse>
***************************************
I prefer to use English rather than a sample for output.

I seek a table each of whose cells contains the count of a sub-set of input
rows such that the sub-sets are mutually exclusive and collectively
exhaustive. This table could be more than two dimensional by repeats in either
row or column display. Each dimension represents sub-set formation according
to one attribute in the input rows.

I wish these sub-sets to be specified by so called “convenience lists” or
RTFs. My code below is successful where one dimension of predicate selector
values, for example, comes from my D1 RTF.

Instead I want to be able to take the whole predicate “name, value” pair
from an RFT. In my prior post, the unsuccessful part was trying to use element
name as the attribute name, and element value as the selection value, but
could not get the syntax correct.

Since I can design the RTF as I wish, should I use attributes within it rather
than element name and element value?
***********code minus formatting aspects
<xsl:variable name="allRows" select="/dsQueryResponse/Rows/Row"/>

<xsl:variable name="D1">
        <GroupAssigned>CRA</GroupAssigned>
        <GroupAssigned>HR</GroupAssigned>
        <GroupAssigned>Legal</GroupAssigned>
</xsl:variable>

<xsl:for-each select="msxsl:node-set($D1)/GroupAssigned">

<td><xsl:value-of select="." /></td>
<xsl:variable name="d1" select="."/>
????could not figure out how to pull @GroupAssigned using info in RTF????
????also, did not understand why replacing $d1 with a dot failed since d1 was
set to dot????
<xsl:variable name="d1Rows" select="$allRows[(_at_)GroupAssigned=$d1]"/>
                
        <xsl:for-each select="msxsl:node-set($D2)/src"> 
        <xsl:variable name="d2" select="."/>
        
                        <xsl:for-each select="msxsl:node-set($D3)/month">       
                        <xsl:variable name="d3" select="."/>
                        <xsl:call-template name="oneCellout">
                        <xsl:with-param name="cnt" 
select="count($d1Rows[(_at_)Source=$d2 and
@FM=$d3])"/>
                        </xsl:call-template>
                        </xsl:for-each>
        </xsl:for-each>

</tr>
</xsl:for-each>

</table>
</xsl:template>

<xsl:template name="oneCellout" >
        <xsl:param name="cnt"/>
        <td><xsl:value-of select="$cnt"/></td>
</xsl:template>
