Re: select attribute in apply-templates

With this xsl:variable syntax (not an empty element with a select
attribute), $y is being created as an object of type result tree
fragment. It is constructed during the execution of the instructions in
the stylesheet.

Here, $y is being addressed as if it were an object of type node-set,
which by definition consists of nodes from the source tree. Per XPath, an
object cannot have its type converted to node-set. This should always
fail in a pure XSLT implementation.

Due to popular demand, vendors have implemented their own methods to
allow a result tree fragment to be converted to a node-set. Check the
docs for your XSL processor.
