Version 3 of the CORBA specs [0] allows an IDL file to incorporate
object state descriptions using the "valuetype" keyword, in addition to
regular interface descriptions.  This allows for objects to be passed
"by value" from the server to a client.  This is something which could
be useful for state capture (e.g. an application can "import" the state
of opened files before being checkpointed) among other things (one could
want to migrate the state of the resources it has on one server to
another server implementing the same service).

Is it to be supported by future releases of IDL4?
