copy of JMI extents

Hi all,

I need a copy operation for JMI packages. Initially I
tried to go through XMI, but this does not work. E.g. if I try to copy
the PrimitiveTypes packages via XMI I get a MalformedXMIException:

  Namespace cannot be resolved: Model

Probably the new XMI API will solve this problem, but I need the
functionality right now.

Hence my question: Is there any copy operation already implemented
which I could reuse ?

I would do it for my own, but it's not a trivial task. Think about the
following situation:

* Class `A' with instance attribute `a' of type `AStruct' having a field
  (or something even more nested inside `AStruct') of type `B'
* Class `B' with instance attribute `b' of type `BStruct' having a field
  (or something even more nested inside `BStruct') of type `A'

In this situation instances of `A' and `B' may reference each other,
so that when the copy is created one of them, e.g. the instance of
`A', must be created first, the place where the instance of `B' has to
be added later on has to be recorded, the instance of `B' has to be
created and then it has to be put somewhere deep inside `AStruct'. This
all is solvable, but it seems really to be an ugly programming task,
so I would be happy if a solution would be already ready out there.
