XSLT broken?

[Mariano Kamp <mk...@codamax.com>]

Hi, 

  I still have the problem, that the XSLT processor invoked from within 
cocoon behaves differently as opposed to be invoked from the command line. 
This happens only when a second namespace is involved. This is the case when 
using the SQLTransformer for example. The nodes are completly omitted when 
using the TRAX Transformer.

  I tried to find a hint in the code with not much of success. Although I 
found that it would work, when there is just one namespace, so I tried to 
patch the SQLTransformer in order to give it a parameter what the output 
namespace should be. Unfortunately even this workaround doesn't work. The 
namespace related to the SQLTransformer is still outputed which breaks the 
TRAX Transformer. 

  Here is what I tried:

Any clue, why it still outputs the namespace of the SQLTransformer? It 
doesn't output any element from the SQLTransformer, but the namespace?!

Any help is strongly appreciated.
