	// The lifetime of the token indirectly depends on the lifetime of the signing
	// key, which is 24h. So delegation tokens can't live longer than 24h.

	// This can match delegated_identity if the user is delegating their own
	// identity or it can be a different id if the token is actually

	//
	// Each item can be an identity string (e.g. "user:<email>"), a "group:<name>"
	// string, or special "*" string which means "Any bearer can use the token".
	Audience []string `protobuf:"bytes,5,rep,name=audience,proto3" json:"audience,omitempty"`

	//
	// List of services (specified as service identities, e.g. "service:app-id")

	Services []string `protobuf:"bytes,6,rep,name=services,proto3" json:"services,omitempty"`
	// Arbitrary key:value pairs embedded into the token by whoever requested it.
	// Convey circumstance of why the token is created.
	//
	// Services that accept the token may use them for additional authorization
	// decisions. Please use extremely carefully, only when you control both sides

	// the tags.
