#### variables in header #####################################################

client_id:
  type: UUID
  in: header
  description: |
    A UUID for each client instance. The UUID must be submitted in its
    canonical form (for example, 3381af92-2b9e-11e3-b191-71861300734c). The
    client generates the Client-ID once. Client-ID persists between restarts
    of the client so the client should reuse that same Client-ID. Note: All
    message-related operations require the use of ``Client-ID`` in the headers
    to ensure that messages are not echoed back to the client that posted
    them, unless the client explicitly requests this.
