If the VA RPC Broker mechanism was a "standard" remote procedure call
mechanism used by compiled languages, I believe that it would include some
way to mark values with their data types. As I recall, the ASN.1 system
was developed for this kind of "rpc" mechanism.

As you point out, the VA RPC broker, uses a specialised protocol for sending
messages. Some of the values are in binary, but I believe the most common
ones are using a simple "string of character" data type. The
Delphi/Java/Visual Basic etc. client then converts the data into the type
that it prefers.
