  definitely non-standard ! Check them at:

  they are not "supported" by xalan or saxon, there have been custom
extension Java modules written to implement those. Very different !

  Get the semantic of that function, write an extension function in C
suitable for xsltproc doing the same and get it integrated :-)

  Another solution is to try to do the extension in python and wrap
up a specific processor based on the python bindings, but it's far
less useful to the community.
