This creates $xmTmplt as a result tree fragment.  Any time the contents of
xsl:variable contain a template-body, you get an RTF, which cannot be used
in XPath expressions as anything but a string unless you use the node-set()
extension function.

A much better way to construct this variable is to use:

<xsl:variable name="xmTmplt" select="document('usr_member.xml')//FLDS"/>

That's still very expensive, especially if it's a large document, but it
will return the desired node-set and you won't have to resort to extension
functions, even though node-set() is supported by nearly all XSLT
processors.
