Re: LSSerializer configuration for namespaces

[Michael Glavassevich <mr...@ca.ibm.com>]

Hi Tommaso,

I've tried this out myself and it appears to be a bug in the Xalan
serializer. You can report the issue here [1]. It is possible to work
around the problem by removing serializer.jar from your classpath. Xerces
will fall back to using its old deprecated serializer if it cannot find the
Xalan one and you should get the result you expected.

Thanks.
