In order to make the use of extensions safe and manageable, 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.","id":"CodeSystem.concept.property.modifierExtension","isModifier":true,"isSummary":true,"mapping":[{"identity":"rim","map":"N/A"}],"max":"*","min":0,"path":"CodeSystem.concept.property.modifierExtension","short":"Extensions that cannot be ignored","type":[{"code":"Extension"}]},{"definition":"A code that is a reference to CodeSystem.property.code.","id":"CodeSystem.concept.property.code","max":"1","min":1,"path":"CodeSystem.concept.property.code","short":"Reference to CodeSystem.property.code","type":[{"code":"code"}]},{"definition":"The value of this property.","id":"CodeSystem.concept.property.value[x]","max":"1","min":1,"path":"CodeSystem.concept.property.value[x]","short":"Value of the property for this concept","type":[{"code":"code"},{"code":"Coding"},{"code":"string"},{"code":"integer"},{"code":"boolean"},{"code":"dateTime"}]},{"contentReference":"#CodeSystem.concept","definition":"Defines children of a concept to produce a hierarchy of concepts.
