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.
