I also struggled with namespaces and I found that in SAXBuilder the fact
that the "namespaces" feature is hardwired to false prevents
correct handling of schemas. Setting the property to true seemed to
solve
the problem. 

This is an issue that I brought to the list but no one answered.
Why is this property hardwired to false ? Why isn't there a way to
programmatically set the property ?


HTH,
