Andy Jefferson commented on JDO-403:
------------------------------------

> 2. I'd like to talk about mapping org.apache.jdo.tck.pc.mylib.PCRect as an
 embedded field. PCRect includes
> two PCPoint instances, so you have to map the embedded PCPoint instances as embedd
ed-embedded

Agreed - nested embedded PC fields aren't catered for in what was provided, 
and your example (but using PCRect/PCPoint as nested embedded) demonstrates 
how it could be done for 1-level of nesting. XML handles this fine since you
 can have <embedded> within
a <field> recursively (down to multiple levels). Annotations have some stran
ge limitation on recursing too (in addition to the other strange limitations
), so not sure if you'll be able to get multi-level recursion (like XML supp
orts). Its the same issue
we have with @FetchGroup and @FetchField

> It would be desirable for JDO2 to have its own set of annotations. We have
 developed a set within JPOX that would likely serve as a starting point for
 such a set. In my opinion they should be
> 1. Split into javax.jdo.annotations.jdo and javax.jdo.annotations.orm
> 2. Move ORM attributes from some of the JDO annotations and have a ORM annotation.
