 "description": "Per-party declaration of fixed operational constants for a served role (Delivery 4.4). The schema is deliberately generic \u2014 it fixes the envelope of a declaration, never the constant names, which each role's specification registers. The first constant registered this way was the introduction mediator's ack-delay (Visibility 8.4); the carrier role of Delivery 4.4 has since registered seven carrier constants, and further roles may register others without touching this file.",
