public @interface ExternalEntity
```
Marks a class as a "stand in" for an external class whose source can not be properly annotated. A class annotated with this annotation will be processed like any class annotated with Entity however, the resulting information stored will reference the target type instead of the annotated type. In this way third party classes can be mapped properly in spite of not having access to the source. See the documentation for more detail.

Developer note.
This is an experimental item. Its function and presence are subject to change. Feedback on features and usability extremely welcome.
