In the SV profile, TopologicalNode.TopologicalIsland is defined. But there is no need to include this in the instance file. The SV profile does not require to put instances of TopologicalNode into the SV File, so the TopologicalNode.TopologicalIsland need not be an optional association in SV profile.<br /></p><p>The "required" [1..1] multiplicity  on an attribute or association (as for TopologicalNode.TopologicalIsland) is suggesting that if an instance of the containing class is included in the message, then the attribute or association must be present. It says nothing about whether or not the instance of TopologicalNode is required in the file.<br /></p><p><br /></p>
