      Description

      JPA 2.0 specifies canonical memtamodel classes for persistent entities. Currently this generation process is uncontrolled.
      Every time the compiler is invoked with

      $ java -processor openjpa.AnnotationProcessor6 my.PObject

      we generate my.PObject_.java.

      We should be able to control this process. In fact, current limitation of being non-selective stops us from activating the service discovery mechanism.

      One suggestion (by Jeremy) is to add a annotation attribute in the @Entity class.
      Another suggestion (by Albert) is to bring this generation process closer to PCEnhancer.

      Can we also make use of the has @Generated annotation timestamp in PObject_.java to make some decisions?
