Reducing list of namespaces in Axis-Generated XML?

[Erich Musick <ma...@erichmusick.com>]

Is there any way to optimize/reduce the list of namespaces in the response
messages generated by AXIS? In the sample response message I've included
below, you'll see that I'm getting the same namespace declaration (
http://somesite.acme.com/types/common) over and over. I'd like to remove
this to minimize my network traffic. It would be ideal if axis would include
the namespace/prefix declaration ONCE in the Envelope tag, instead of
everytime it uses an element belonging to that namespace.

I'm using AXIS1 1.4.

Thanks!
