Lift requirement that MappedSuperclass, Entity and Embeddable classes must be top-level classes

[lukasj]

Currently, JPA Specification 2.1, section 2.1, paragraph 3, states:

The entity class must be a top-level class

The section on @embeddable classes, in turn, refers to that section.
It is my assumption that it would be quite safe also to allow static nested classes without posing too much problems to implementations.
So, I suggest to lift that requirement such that static nested classes are allowed as entities and/or embeddables.
