    This file contains just the constraints for the resource AdministrableProductDefinition
    It is provided for documentation purposes. When actually validating,
    always use fhir-invariants.sch (because of the way containment works)
    Alternatively you can use this file to build a smaller version of
    fhir-invariants.sch (the contents are identical; only include those 
    resources relevant to your implementation).
