Re: Setting variable based on passed in parameter

I ran into the exact same problem as Matthew.  As Richard said, your
processor probably has a "node-set" function that you can call to turn a
"result tree fragment" into a node set.  In MSXML4 I had to do this:

<xsl:stylesheet
	version="1.0"
	xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
	xmlns:msxsl="urn:schemas-microsoft-com:xslt">

The last line of that is what matters for using "node-set".

And then I called node-set like this:

   select="msxsl:node-set($fragment_variable)"

or similar.

EXSLT provides the function exslt:node-set(some-node-set) (in the
namespace xmlns:exslt="http://exslt.org/common", but only if your
processor supports it) which turns a variable into a node set. Its
quite
expensive, though.
