what you want to do in your logicsheet is something like this:

<xsl:apply-templates select="ls:setTerminalId/*"/>

instead of

<xsl:apply-templates select="ls:setTerminalId"/>

If the element in question might have text, or might have elements from
other logicsheets, and you don't know which or what, you might try
something like this:

<xsl:call-template name="get-nested-string">
 <xsl:with-param name="content" select="ls:setTerminalId"/>

<xsl:template name="get-nested-string">
 <xsl:param name="content"/>
 <xsl:for-each select="$content/node()">
   <xsl:when test="name(.)">
    + <xsl:apply-templates select="."/>
    + "<xsl:value-of select="."/>"

(partially based on the get-nested-string method ricardo wrote for the sql
logicsheet, in turn based on the get-nested-content method ricardo wrote
for all of the other logicsheets)

i just struggled through this issue for a site of mine. it's not
immediately intuitive, but after a while you'll grok it.

honestly, this is the only thing that really worries me about XSP - some
things that you would think would be really simple are in fact subtly
tricky - never impossible, mind, just nonintuitive. i guess that's where
we need more and better docs. hey, someone was working on an XSP tutorial
but it never got linked off of cocoon's site. can the party responsible
repost the link and i'll add it to the web site myself? merci.
