Saxon is not in cause in this problem (or maybe only for the xmlns:xml
declaration) and is compliant with the XSLT spec, while Xalan has some
bugs with the namespace:: axis and the XSP engine "relies" on this bug.
I patched the XSP engine for Cocoon 2 to avoid all these extraneous
declarations, and obviously Cocoon 1 users need this patch also. I'll
try to do it ASAP (I'm really busy these days, so don't expect it before
tomorrow) and will notify you when it's done.
