Assuming you're working with XSLT 1.0, this is an extreme FAQ.  Variables
that contain template bodies always return a result tree fragment (RTF)--and
there is no way to cast such variables to a node-set without resorting to
the node-set() extension function that's available with most processors.

One way to fix this would be to use a select attribute on the variable:

<xsl:variable name="t" select="y"/>

Assuming y is a valid node in your input, you can now write:

<a href="..."><xsl:copy-of select="$t"/></a>

copy-of will write $t including its child nodes to the result tree; value-of
will only copy its textual content--child elements are ignored.
