What implementations of XPath 3.0 exist at present?

[Dimitre Novatchev <dnovatchev@gmail.com>]

I am trying to get a more or less exact number of the currently
existing implementations of XPath 3.0.

The ones I am aware of are:

Saxon 9 (XSLT 3.0 and XQuery 3.0)

Mark Logic (XQuery 3.0, ??XSLT 3.0??)

BaseX  (XQuery 3.0, ??XSLT 3.0??)

Zorba ???

ExistDb ???

other ???

Which of these implementations are commercial and which have free
and/or open source versions? I know that BaseX is open source, what
about the rest of the existing XPath 3.0 implementations?

Could you, please, help in filling up this list -- I believe that such
information would be interesting and useful for all of us.
