Versioning of Web Services prior to EHP1

Hi!

Right now we are working on PI 7.1 and we wish to have some version control on our web services. I cannot find any explicit versioning system for services in the Service Registry.

Basically I would like to be able to set a Web Service as "deprecated" or similar, if I develop non-backwards-compatible changes.

In EHP1 there are introduced some functionality for versioning of WebServices, but my question is how has this be done prior to EHP1? Anyone experienced this, and is there maybe some other way to solve this?

Thanks!

regards Ole
