Since the OXM stuff from Spring-WS has now been incorporated into Spring 3, Spring-WS will at some point need to be updated to use the OXM code from the core framework. The OXM code in the core has already moved on, and is newer than that in Spring-WS.
I am currently developing a system using Spring 3 M4 and Spring-WS 1.5.x, and I have to be very careful not to include the OXM code from Spring-WS in the build. When Spring 3 goes final, this will become increasingly problematic as prople try to use them together.
When would you propose making this leap? Perhaps a 1.6 version bump?
