Altova: Free XSLT1.0/XSLT2.0 and XQuery1.0 Processors for Windows

Breaking news from Altova GmbH (maker of famous XML Spy IDE):

Altova has compiled a collection of free tools and technical resources to help develop solutions for today's business challenges.

XSLT and XQuery ones are the new and the most interesting. Altova XSLT 1.0 engine is well-known XSLT engine used when debugging XSLT within XML Spy, now they just release it as a free (but not open-source of course) standalone utility (Windows 2000/XP/2003 command line executable), "suitable for use in both client- and server-side application development". Altova XSLT 2.0 engine is a similar utility, which claims to implement November 2003 XSLT 2.0 working draft. It's schema-unaware processor and doesn't support user defined types and validation. Some functions and elements aren't supported either (yet?).

Altova XQuery Engine is also available as free command line Windows 2000/XP/2003 exe, which implements July 2004 XQuery 1.0 working draft. The same here - no support for schema importing, validation and user-defined types. No support for static type checking, external functions, character normalization either. XQuery library modules are supported though. More info about limitations here.

The tools are available "for you to use both for your own purposes and to integrate into your solutions without paying any royalties or license fees." The license: Altova XSLT/XQuery Engine developer license agreement.

Sounds awesome. I just downloaded the tools, but didn't give them a whirl yet. I wonder why there is no support for schema, actually XML Spy has a very decent schema processor for years now. Hmmm, very cool tools anyway.
