element definition.definition:

Though any implementer can define an extension, there is a set of requirements that SHALL be met as part of the definition of the extension.
element definition.comment:
  value: 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.

element definition.definition:

Though any implementer can define an extension, there is a set of requirements that SHALL be met as part of the definition of the extension.
element definition.comment:
  value: 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.
