There is no fully portable solution in XSLT 1.0.

You can make this slightly more portable by using the EXSLT node-set
extension function instead. EXSLT is a "standard non-standard" set of
extension functions which is supported by a number of XSLT processors,
Xalan among them. It isn't fully generic, but at least it improves the odds
that your processor will understand the request.

The truly generic solution will be XSLT 2.0, where the distinction between
node sets and source trees and result tree fragments will be eliminated.
