Documentation List of values on a uniform nominal scale. List of text tokens. In a list context a token should not include any spaces, so xsd:Name is used instead of xsd:string. A member of the list may be a typed null. If a codeSpace attribute is present, then its value is a reference to a Reference System for the value, a dictionary or code list.
