Thanks to Antonio Mota, Michael Kay, Evan Lenz, and David Carlisle for
responding to my question.  The solution ultimately employed looked like
this:

<xsl:for-each select="descendant::text[@id and count(ancestor::system) =
$sysCo]">

where $sysCo is set equal to: count(ancestor::system)

Subject: [xsl] excluding descendants (and all of their descendants as
well)


How does one find all text elements that are descendants of the first para
element but exclude any text element that is a descendant of the second system
element?

<techinfo>
  <system>
    <descinfo>
      <para-seq>
        <para>
          <text>The quick brown fox jumped over the lazy systems
engineer.</text>
          <text>Hello world.</text>
          <style>
            <text>In the matter of Jardyce v. Jardyce:</text>
          </style>
          <system>
             <descinfo>
                 <para-seq>
                     <para>
                          <text>Blah, blah, blah...</text>
                           <text>more gibberish.</text>
                           <style>
                               <text>Nasty, Brutish, and Short Attorneys at
Law</text>
                           </style>
                        </para>
                      </para-seq>
                  </descinfo>
               </system>
            </para>
         </para-seq>
      </descinfo>
   </system>
</techinfo>

Thanks very much.
