Ken,

If I'm understanding what you want:

  -> a reusable "chunk" of tags and <xsl:***> elements
   
  -> that is responsible for handling the formatting for
     the "ChargeListRSQ" block of your source document 

  -> In a way that allows the "chunk" of tags to
     use xpath expressions that are relative to the 
     "ChargeListRSQ"

  -> Without mentioning a particular XML file that <ChargeListRSQ>
     "lives in"...

Then an <xsl:template> can do all these for you.

Let's say your data looks like this:

<TR300>
  <ChargeListRSQ>
     <Charge id="1">ABC</Charge>
     <Charge id="2">DEF</Charge>
  </ChargeListRSQ>
</TR300>

Then you can create a "tab.xsl" stylesheet with a template
whose match pattern is match="ChargeListRSQ", and it will 

<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"; version="1.0">

   <!-- This template handles ChargeListRSQ "block" -->
   <xsl:template match='ChargeListRSQ'>
     <table border="1">
        <xsl:for-each select="Charge">
          <tr>
             <td><xsl:value-of select="@id"/></td>
             <td><xsl:value-of select="."/></td>
          </tr>
        </xsl:for-each>
     </table>
   </xsl:template>

</xsl:stylesheet>

and then include "tab.xsl" into another main stylesheet like "main.xsl"...

  <xsl:output method="html" indent="yes"/>

  <xsl:include href="tab.xsl"/>

  <xsl:template match="/">
    <html>
      <body>
         <xsl:apply-templates/>
      </body>
    </html>
  </xsl:template>

</xsl:stylesheet>

And by the magic of the "Apply Templates" processing, when it comes
time for handle the formatting for the <ChargeListRSQ> in the source,
your template will "fire" and your reusable chunk of tags will kick in.
