Parser failure with validate=true when processing stylesheet

           Summary: Parser failure with validate=true when processing
                    stylesheet
           Product: Cocoon 2
           Version: 2.1alpha CVS
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: Major
          Priority: Other
         Component: core
        AssignedTo: cocoon-dev@xml.apache.org
        ReportedBy: crossley@indexgeo.com.au


Problem
-------
Recently we were able to switch on validate=true during "build docs" to enable
validation of Cocoon's own xdocs. That was working beautifully to detect any
errors that may have crept into CVS.
 
Then a bug was fixed in XSLTProcessorImpl.java that had been disguising this
current bug. The exceptions described below were suddenly thrown when trying to
use the "validate=true" option.
 
It seems that Xerces is getting confused about the namespace declaration in the
stylesheets.
 
Description
-----------
In mid-January, a bug was discovered and fixed in
cocoon/components/xslt/XSLTProcessorImpl.java - Revision 1.5
VG> I discovered that XSLTProcessorImpl code have some flaws,
> like it is not using toSAX method of the Source interface, thus
> requiring to serialize and then parse again XML (result: slower
> processing of cocoon: protocol).

We presume that a separate parser was being used by XSLTProcessorImpl.java
and that parser did not have the "validate" parameter set. Now that the
default parser is being used (which has "validate=true") the exceptions start
to appear.
