  • Summary:

    Subclause: 8.3.15: Sequence Construction Expressions

    In Subclause 8.3.15, the parsing of a NullExpression should set the hasMultiplicity=true for the SequenceConstructionExpression, otherwise the derivation of the lower and upper attributes (see Subclause 13.2.46) will result in those both being 1 instead of both being 0.
