FYI: I wrote some similar functionality for RHQ's bundle upgrade capability. Based on that experience, I would recommend to whomever is implementing this new AS7 patch feature to review  RPM's upgrade rules to see how RPM does things - this is very helpful to see the different types of conflicts you can expect and how to resolve them:

RHQ's upgrade rules ended up being very similar:

Hopefully, those wikis can be helpful.
