KERML_ — Redundancy in association end multiplicities, ordering, and uniqueness

KerML association end textual notation/abstract syntax give multiplicity, ordering, and uniqueness that can be redundantly stated on the corresponding features of associated classifiers (association ends in SysML1.x/UML sense, see KERML_-16 about terms), eg, in Occurrences:

Occurrence::suboccurrences [1..*] {...}

HappensDuring {end shorterOccurrence [1..*] subsets longerOccurrence.suboccurrences;}

making it possible for multiplicities, ordering, and uniqueness to get out synch between the features, and potentially be inconsistent. See kerml-assoc-redundancy-issue-description-v2.pdf slides attached.
