  • Disposition Summary:

    Correct language description

    The identified statement in 7.4.5 is incorrect. In addition, there is a similar statement about connectors in 7.4.6.1 ("Connectors with more than two connector ends ("n-ary") have only target features, no source features.") that also contradicts the normative constraints deriveConnectorSourceFeature and deriveConnectorTargetFeature.
