Is there a way in XSL to take an XPath query described in a parameter or variable, and reference this parameter in the select attribute of say, xsl:for-each to iterate through the node set described by the query.

ie.

<xsl:variable name="myPath" select="'/my/XPath/@query'"/>
<xsl:for-each select="{$myPath}">
        ...
</xsl:for-each>

We were under the impression that using the curly braces might achieve this, but haven't had any luck so far.
