It is absolutely bleeding edge, yes, and bug reports are welcome.

However, until PyXML is released with these packages, you should not
assume that they actually work. Indeed, one possible scenario is that
the next PyXML release does *not* included these subdirectories.

Neither, nor. 4XSLT uses a different XPath expression parser than the
copy in PyXML; the 4XSLT one is based on BisonGen/SWIG/bison/flex; the
PyXML one (dubbed PyXPath) uses Yapps/(s)re. The port to the other
parser, as well as other DOM implementations, is not complete.

A number of reasons. First of all, Fourthought has not contributed
them (although they might if asked). Then, the tests do require a
4Suite installation at the moment. Finally, the tests don't pass
without modifications; I'd like to minimize the necessary changes
before incorporating tests.
