This is the subject of extension functions and extension elements, defined
in section 14 of the August working draft:
http://www.w3.org/TR/xslt#extension

James Clark's XT is an XSL processor that implements the working draft using
Java. I would point you to the extension function examples on his XT page at
http://www.jclark.com/xml/xt.html but it seems to have gone missing!

Michael Kay's SAXON is an XSL processor that implements extension functions
in a similar, yet slightly different, way.
