CORBA35 — OBV "chunking"

Summary: The OBV spec adds the notion of "chunking" because it claims that "it is
anticipated that value types may be rather large, particularly when a graph
is being transmitted. Hence the encoding supports the breaking up of the
serialization into an arbitrary number of "chunks" in order to facilitate
incremental processing." (orbos/98-01-18, page 5-55)

This "feature" should be removed from the spec, since it is the job of the
underlying transport to handle this issue. GIOP already provides
fragmentation, allowing transports to handle large parameters efficiently
– why should we build yet another fragmentation solution on top of it?
