notation for referencing these types and for specifying values of these types;<\/p>\n<\/li>\n<li>\n<p>defines mechanisms for constructing new types from more basic types, and specifies a notation for defining such types and assigning them tags, and for specifying values of these types;<\/p>\n<\/li>\n<li>\n<p>defines character sets (by reference to other Recommendations and\/or International
