Thanks Martin. Works great.

Using XSLT 1.0 and MSXML I've run into the
limitation
of an improper use of a result tree fragment. I'm
creating a variable, "confirm_active_program" that
contains some number of <program> elements like
so:

<program active="true"/>
<program active="false"/>

I then have a choose statement which contains a
when
test:

<xsl:when
test="not($confirm_active_program/program[(_at_)active
=
'true'])">...</xsl:when>

The only error I'm getting is that the expression
requires a node-set. Going back and reading on
RTFs in
1.0 I realize this isn't going to work. Is there
any
other way to accomplish my desired effect in 1.0?

MSXML supports an extension function to convert a
result tree fragment 
into a node-set, the function is named node-set and
is in the namespace 
urn:schemas-microsoft-com:xslt so you can do e.g.
   <xsl:variable name="v1"
     xmlns:msxsl="urn:schemas-microsoft-com:xslt" 
select="msxsl:node-set($confirm_active_program)"/>
   <xsl:when test="not($v1/program[(_at_)active =
'true'])">
