The most portable way of doing this is to use the document() function with a URI of your own invention, along with a URIResolver that returns the result in the form of a DOMSource, SAXSource, or StreamSource object. This is a bit tricky, though, if your function has complex parameters. In this case you are stuck with using extension functions, and each XSLT processor has its own rules for what arguments and return values it accepts. Many XSLT processors will only accept DOM nodes that were created by the same product, e.g. if you use the Oracle XSLT processor you have to use the Oracle DOM implementation. Recent release of Saxon allow an extension function to return a DOMSource, which can wrap any DOM - but it's expensive.
