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.        Applications processing a resource are required to check for modifier extensions.  Modifier extensions SHALL NOT change the meaning of any elements on Resource or        DomainResource (including cannot change the meaning of modifierExtension itself).",
        "comment": "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.",
        "requirements": "Modifier extensions allow for extensions that *cannot* be safely ignored to be        clearly distinguished from the vast majority of extensions which can be safely        ignored.  This promotes interoperability by eliminating the need for implementers        to prohibit the presence of extensions. For further information, see the [definition        of modifier extensions](extensibility.html#modifierExtension).",
