Issue 19: Stream contexts and internalization (externalization)

Summary: The Externalization spec does not state how a stream implementation is to discover that a context exists when internalizing an object.

Summary: The standard stream data format does not define tags to be used to identify the beginning and end of a context.

Summary: The standard stream format should specify that it is portable across different ORBs and hardware, but not across streamable object implementations whch use different semantic content.

Summary: What happens when multiple calls are made to Stream::externalize() at the top level? Does the stream contain all those objects, and how does a client discover this?

Summary: When reading a stream, there is no way of telling where context (limited to calls to begin_context and end_context) end and a new one starts.. Resolved problem with new "tag-byte" 0xFF.

Summary: When Node::externalize_node is called, is node responsible for externalizing related object? What happens, if related object isn"t a CosStream::Streamable?

Summary: Role in new node are disconnected It"s role of read_graph to correctly establish new relationships. How is that accomplished?

Summary: When internalizing a relationships, how do the "shallow" nodes and roles get included?

Summary: The IDL for internalizing roles could be optimized to reduce the size of the externalized data as well as simplifying the implementation

Summary: Circular refrences to CosStream and CosCompoundExternalization,
 i have not been able to find an idl compiler that can compile
 these modules.
 
 as aside, i have foud many syntax errors in the IDL you provide
 as CORBAServices98-03-02.idl, in many of its interfaces, there are
 typos, and it is not correct with the specifications.
