Here, $query is a result tree fragment.
(Not a string, as you assumed).

Here, $query must be a node-set.

The only way to make a variable be a node-set is to
put a node-set-selecting XPath expression in the
select attribute of the xsl:param or xsl:variable
element.

You can write an extension function that takes the
string value of a data object and returns a node-set
based on evaluation of the string as an XPath
expression. :)

But no, there's nothing built-in to XSLT that will
let you do what you want.
