I want to list all Activity sub-diagrams as shown below, with commas separating each name. However, the breakString property is not supported. Please add it to ForEachSubDiagram and any other loop tags that may be missing it.
<ForEachSubDiagram diagramType="ActivityDiagram" ignoreLastSeparator="true" breakString=", ">
<Sortings noSort="true"/>
<Property property="name"/>
</ForEachSubDiagram>
