This collection implements various extension elements and functions for libxslt that have proved useful in a few projects. The functions or elements actually implemented follow no particular plan, rather they are somewhat randomly chosen based on immediate need over time.

They attempt to follow the specifications from exslt.org or XPath 2.0 functions where feasible, although some functions appear in neither specification. Since XPath 2.0 has a number of features not present in the libxml2 implementation, corresponding implementations are at most similar rather than identical.
