Since hope of convergence on these any time soon appears to be dim,
I am going to remove copy and merge graphs from the Public Draft.
While we can certainly continue to discuss the issues and/or alternatives,
this makes it unlikely that we would be able to include such functionality
in JPA 2.1.
The use of entity graphs as fetch and load graphs will remain.
I'll try to post an updated spec and javadocs by later today.
