Yes, provided $varname is a node-set. For example, you can write:

<xsl:variable name="v" select="//para[starts-with(., "The ")]"/>
<xsl:apply-templates select="$v">

to process all paragraphs whose text starts with "The ".

You can't do this if $varname is a result tree fragment, except by using an
extension function such as the node-set() function provided by both xt and
Saxon.

Neither of which is proprietary, by the way, they are both open source. But
I know what you mean.
