William (Bill?),

As I just posted, the space makes no difference as to whether a variable refers to a node set or to an RTF. It's all in how the variable is declared.

<xsl:variable name="node-set" select="/node/set"/>

<xsl:variable name="RTF">
  <xsl:copy-of select="/node/set"/>
</xsl:variable>

$RTF holds a result tree fragment. Note that the instruction xsl:copy-of creates a *copy* of the node set. In XSLT 1.0, all such copies are RTFs. But in general, any variable you bind by inserting element content into the variable element creates an RTF.

$node-set holds a node set. That is because this is the type of data object returned by the XPath expression in the select attribute. Had it said select="false()", the variable would refer to a Boolean value, and so forth.

For more on your particular problem, you've seen that earlier post by now, probably.

Cheers,
Wendell
