  title: ServiceCoordinationOffer Schema
  version: "2.1.0"
  description: >
    Offer-level attributes for a coordination engagement in the generalised Beckn
    Protocol model. Extends ServiceOffer/v2.1 with the coordinator's terms for
    accepting a coordination engagement — per-urgency SLA windows, its retry policy
    on downstream refusal, whether it supports transfer of an in-flight coordination
    to another coordinator, and an optional capacity signal. Inherited base fields
    (minimumQuantity, maximumQuantity, requiresAdvanceBooking, bulkDiscountAvailable,
    eligibilityCriteria, validityPeriodDays, cancellationPolicies) come from
    ServiceOffer/v2.1.

    All fields are advisory and optional — the offer carries the coordinator's terms,
    not mandatory data. An absent or empty ServiceCoordinationOffer is valid and means
    "no special coordination terms"; the base ServiceOffer/v2.1 defaults apply.
