  • Disposition Summary:

    Resolution: Multiassociation

    The reporter confounds n-ary associations with multibranch associations. SysML only support binary associations, i.e. associations with exactly two association ends. The metamodel support for n-ary associations has been excluded from SysML.

    Multibranch associations are a notational variant of two or more binary associations that have each an association end with the same property specification.
