Should an error be thrown if a class is annotated with @Entity and @Embeddable?

Working on a JPA compliancy kit for my internship... Part of that kit is testing all corner cases.

I'm looking at @Embeddable today. No attributes to deal with.

Then I started wondering...

What if a class is annotated with both @Entity and @Embeddable? I found this related question A class that behaves like @Entity and @Embeddable that states JPA does not allows @Entity and @Embeddable at the same time. However, he's doing this in the context of an @ElementCollection, which is my guess as to what would be causing JPA not to like it (can't stuff non basic/embeddable types in there).

Basically, According to JPA 2.0, Should an error be thrown if a class is annotated with both @Entity and @Embeddable? If not, what should happen?

From page 323 of JSR-317:

Managed class to be included in the persistence unit and to scan for annotations. It should be annotated with either @Entity, @Embeddable or @MappedSuperclass.

This is in reference to managed class definitions in a persistence unit. Based off that I do not believe it is valid to annotate a class with more than one of @Entity, @Embeddable or @MappedSuperclass.
