8. ContactPoint.use.extension
Definition	An Extension May be used to represent additional information that is not part of the basic definition of the element.

Short	ExtensionAdditional content defined by implementations
Comments	There can be no stigma associated with the use of extensions by any application, project, or standard - regardless of the institution or jurisdiction that uses or defines the extensions. The use of extensions is what allows the FHIR specification to retain a core level of simplicity for everyone.
