TargetScope
class TargetScope @InternalWowApi constructor(val tenantId: String? = null, val scope: Scope = Scope.NONE)
The tenant and scope a caller with me.ahoo.wow.api.caller.Caller.crossScope asks to act in instead of its own (the Wow-Scope header): tenantId, when given, replaces the caller's tenant, and scope replaces the caller's scope as a whole, so a part it leaves out is not checked against the aggregate.
Fields may be added: construct one with of; the constructor is internal to Wow.
