With version 1.2 it doesn't work as with version 1.3rc1. But I didnt try
all versions, only 1.1.2, 1.2 and 1.3rc1, so I don't know exactly in
which version the "error" was introduced.
Without making confusions it seems that the xerces version also plays a
role. If I run the code with xerces version 2.8.1 then the actually
working declarating
<root xmlns="first/namespace" xmlns:other="other/namespace">
also produce the error message above. If I use the newer version 2.9.1
then there is no error.
Because I need that my code is running right know I replaced the
two-namespace-schema with one having only one namespace.
Best Regards
