It's an additional element in a returned complex type. New operations
appear to be safe (and the client cannot call them, of course), as do new
complex types (as long as they're not serialized to the client).
Essentially anything that is serialized to the client that it did not know
about beforehand is a problem, yielding XML deserialization exceptions.
Seems unreasonable that the server should know every client's version
compatibility and somehow deliberately not serialize 'new' elements.
Axis version is 1.3 final.

Jarmo-
do you see this as an attribute or independent element?
In either case its a good idea to know the version of Axis being supported
