Title : Extensible XDR Discriminated Union Primitive Type Author(s) : Thomas Keiser Andrew Deason Filename : draft-keiser-afs3-xdr-union-06.txt Pages : 11 Date : 2012-09-10 Abstract: AFS-3 relies upon XDR to carry Rx RPC call payloads. XDR discriminated unions are ill-suited to cases where the protocol needs to evolve without inventing new RPCs, i.e., unknown discriminant values cause the entire XDR payload to fail the decoding step. While this can be circumvented through the use of opaque payloads (and recursive XDR invocations), such solutions are inelegant and difficult to implement. This memo defines a new XDR primitive type, "ext-union", which is derived from the XDR discriminated union primitive type, but with two key variations: 1) each leg contains a length field, and 2) no default leg is supported.
