// ReferenceGrant identifies kinds of resources in other namespaces that are
// trusted to reference the specified kinds of resources in the same namespace
// as the policy.
//
// Each ReferenceGrant can be used to represent a unique trust relationship.
// Additional Reference Grants can be used to add to the set of trusted
// sources of inbound references for the namespace they are defined within.
//
// A ReferenceGrant is required for all cross-namespace references in Gateway API
// (with the exception of cross-namespace Route-Gateway attachment, which is
// governed by the AllowedRoutes configuration on the Gateway, and cross-namespace
// Service ParentRefs on a "consumer" mesh Route, which defines routing rules
// applicable only to workloads in the Route namespace). ReferenceGrants allowing
// a reference from a Route to a Service are only applicable to BackendRefs.
//
// ReferenceGrant is a form of runtime verification allowing users to assert
// which cross-namespace object references are permitted. Implementations that
// support ReferenceGrant MUST NOT permit cross-namespace references which have
// no grant, and MUST respond to the removal of a grant by revoking the access
// that the grant allowed.
