A Parametric diagram includes the usage of a Constraint Blockto constrain the properties of other Services. It contains Constraint Propertiesand Constraint Parameters as well as other properties (Service Roles or Measurements) from within that internal Service context. All properties displayed other than the constraints themselves, must either be bound directly to a Constraint Parameter or contain a property that is bound to a Constraint Parameter (through any number of containment levels). A Constraint Block generally contains many constraints, each of them containing many Constraint Parameters.
