ITU-T X.680 (1997) Technical Cor. 1 (06/1999)

This technical corrigendum to ITU-T Rec. X.680 | ISO/IEC 8824-1:a) clarifies what characters are in the ASN.1 character set;b) clarifies what is meant by the terms "white-space character" and "new-line character";c) clarifies the effect of subtype constraints when used in conjunction with the "COMPONENTS OF" and SelectionType notations;d) corrects the production for "ElementSetSpecs" so that the syntax does not allow types that can have no value;e) makes it clear that when a range is used in specifying a "PermittedAlphabet", the lower and upper bound must each be a single character;f) clarifies the requirement for tag uniqueness when the extension insertion point is not at the end of the sequence type;g) makes several editorial corrections.
