An abstract data type whose specification otherwise conforms to the ISO 21090 representation of a name for a person, organization, place or thing. Structurally entity names are sequences of entity name parts, but in addition the data type provides support for specifying the valid period of a name and its intended use. ## Specializes ## ANY ## Attributes
