I believe Xalan handles other extension languages though the Bean Scripting
Framework (BSF), which provides a single API for many scripting languages.
You need a BSF driver for the language you're intrerested in using (I'm not
sure whether VBScript is one of those included in the standard package
these days). Then you have to write your extension code so it conforms to
the BSF conventions as implemented by that driver.
For more info about BSF, see http://www.ibm.com/developerworks/oss/ and
select BSF from the "select a project" drop-down list. (You _may_ be able
to get there faster via http://www-124.ibm.com/developerworks/projects/bsf)
