Generating HTML documentation from WSDL

I tried several alternatives

• TechWriter for Web Services: Really powerful, but HTML output was (see comments) multi-file. Also, comments indicate it is retired, but that is no longer the case.
• <oXygen/> XML Editor: It doesn't process embedded schema.
• Altova XML Spy: It doesn't process anonymous types.

and ended up tweaking WSDL viewer to my needs.

Use http://code.google.com/p/wsdl-viewer/ and cygwin's xsltproc

xsltproc wsdl-viewer.xsl downloaded-wsdl.xml > documetnation.html

Works like a charm

Yes, there is a new one: wsdl2html. It focuses on request/response and removes info that people don't care.
