Target namespace in published webservice

It seems that the target namespace is not handled in the documentation of the published webservice. Could somebody from Mendix explain if and how this is used? Now it does not seem to matter what I fill in here. Or do I miss something? Regards, Ronald [EDIT] Thanks for all the info. Also found a website with some clarification. The only thing I still not grasp is if the URI should be difference for the test, acceptance and production webservice.

Each XML Web service needs a unique namespace in order for client applications to distinguish it from other services on the Web. is set by default for XML Web services that are under development, but published XML Web services should use a more permanent namespace.
