Then this is a good use case, which shows that we need the following:

<xsl:reference-of select="$xpathExpression"/>

This is the counterpart of xsl:copy-of. For each node in $xpathExpression its reference will be
generated.

By definition, a node-set containing references ("reference-set"???) will be indistinguishable
from a nodeset containing the original nodes.

It would be nice if someone could point out any anomalies/contradictions in using this approach.
