       and managable, there is a strict set of governance applied to the definition and
       use of extensions. Though any implementer is allowed to define an extension, there
       is a set of requirements that SHALL be met as part of the definition of the extension.
       Applications processing a resource are required to check for modifier extensions.

       project, or standard - regardless of the institution or jurisdiction that uses
