The latest Cocoon CVS HEAD (2.1) is working again, but...
Read details below:
After I spent a few hours trying to debug the problem,
I realized that there is an issue with Xerces 2.2.0 and 2.2.1 (or
incompatibility between it and the new Xalan libs).
I rolled back to Xerces 2.1.0 and things are looking good again.
I kept the latest versions of Xalan.
The combination appears to work well.
As far as XSLTC is concerned, there appears to be a difference in the
behaviour between its latest version and Xalan.
I am attaching two html files, result from XSLTC and Xalan applied against
the same xml source file.
The stylesheet is also attached.
Xalan produces the results that I would like to see,
although it is possible that my stylesheet is buggy.
Until now all XMLForm demo pages have been working equally good with both
XSLTC and Xalan.
I will now have to switch the demo to Xalan until this difference in the
translators is resolved.
If anybody has a better diagnostics of the problem, please notify the Xalan
group of your findings.
Cheers,
Ivelin

<!--
Basic XMLForm processing stylesheet.
Converts XMLForm tags to HTML tags.
Syntax is borrowed from the XForms standard.
http://www.w3.org/TR/2002/WD-xforms-20020118/
This stylesheet is usually applied at the end of a
transformation process after laying out the xmlform
tags on the page is complete. At this stage xmlform tags
are rendered in device specific format.
Different widgets are broken into templates
to allow customization in importing stylesheets
