Hello list,
I've put together a little site of the standard XPath 3.0 functions,
specially designed to be used as reference for every day coding. The
content was copied from the W3C spec, which links back for additional
topics and related specs. The code that generates the site is open
source, in case anyone is interested. Here it is:

Happy coding.
