Re: [xsl] Param Element

[David Carlisle <davidc@xxxxxxxxx>]

   It is working...

This seems unlikely.

   I'm still a little confused on the parm(s) but no worries!

 <xsl:apply-templates select="row"/>
 <xsl:template match="row">
  <xsl:copy-of select="."/>
 </xsl:template>
 
is equivalent (but slower, probably) to
<xsl:copy-of select="row"/>
it just copies all the row elements. In this case however it prduces
nothing as there are no row element children of the current node (the
only child of / is a in_proc element (I guess, you have not shown your
input format)

 <xsl:if test="$current_id = $activity_id">
this test is always true (given the default value of $xm) as $current_id
is an attribute node from the set $activity_id
Even if you supply an xm parameter so that the tests may be false, 

 <xsl:apply-templates select="$xm/row" mode="append"/>
 <xsl:template match="row" mode="append">
  <xsl:variable name="current_id" select="@id"/>
  <xsl:if test="$current_id = $activity_id">
    <xsl:copy-of select="."/>
  </xsl:if>
 </xsl:template>

is equivalent to

<xsl:copy-of select="$xm/row[@id = $activity_id]"/>
