CTS2F2 — CTS2: Change cardinality of defaultLanguage from [0..1] to [0..*]

11-09-02 CTS2 Code System and Code System Version Catalog Services

On page 16 the attribute of the CodeSystemCatalogVersionEntry the defaultLanguage is defined as the default spoken or written language used in this version. If we look at the cardinality we see it is [0..1]. We believe this should be [0..*]. HL7 CTS2 specifies " The different languages (supportedLanguages) supported by the Code System in this version". For certain official terminology providers the same version can be multilingual. For example the file supplied by ISO ISO-639-2_utf-8.txt is both in English and in French. STS implements the attribute supportedLanguages as a list of languages, which we believe is much more fitted than a defaultLanguage attribute (with only one language). Proposition: Change cardinality.
