Hi Michael,

So there is (quite) some development then. Intriguing that parties decide to create XSLT 2.0 processors as part of larger products, instead of developing it as stand-alone products. When few parties take on the development of a new standard, it is easy to jump to conclusions about its life expectancy. This sure sounds that XSLT 2.0 still is alive and kicking!

Gestalt is still there, but with no further development.

Oracle and Microsoft have made no further moves, as far as one can see.

IBM have announced their XSLT 2.0 processor, available as part of Websphere.

Intel have announced their XSLT 2.0 processor, available as part of SOA

I have heard rumours of two or three other processors that are under
development, but I have no idea when (if ever) they will see the light of

Happy New Year to everybody!

While slowly getting my hands back into XSLT 2.0 again, I was wondering whether the past one and a half years (yes, I admit, I was a bit "out") any new XSLT 2.0 processor or plan thereof has seen the light. Here's what my memory gives and what I deducted from my copy of the xsl-list:

-- Gestalt, Eiffel XSLT 2.0 processor far in progress, but ceased further development in Nov. 2008, open source
-- Saxon, Java XSLT 2.0 SA and Basic, fully functional, both commercial and open source editions
-- Altova, XSLT 2.0 command line only (aka AltovaXML), fully functional, known bugs, closed source, free
-- Oracle 10g XSLT 2.0 processor, closed source, free separate download, unclear development status, pre-Rec
-- Microsoft had plans for XSLT 2.0 for .NET 3.5, but no real new news seen since, not included in .NET 4.0
-- XSLT 2.0 features implemented with XSLT 1.0: remember the plan, can't seem to find it, it would be limited though

That is: 4 processors actually developed, some half-baked plans, one (two if we count SA + B double) real XSLT 2.0 processor, one XSLT 2.0 commercial processor (AltovaXML) with a disputed reputation and reliability. Is that the current status still? Does anybody know of another commercial or open implementation that's missing from this list?

I'm particularly surprised about MS, esp. now that more and more of their new technology is based on XSLT and XML. Internally, they've implemented the XPath 2.0 datamodel, but that's all so far it seems.

Kind regards to everyone,
