Description Enda O Brien CLA 2022-02-04 07:17:18 EST 
The markerSupport extension contains a method of creating custom marker groupings.
However it does not appear to be possible to implement handling without referring to the internal GroupsContribution class as follows for example.

<menu
   id="problemsGroupByMenu"
   label="%MarkerGroupMenu.GroupBy">
    <dynamic
          class="org.eclipse.ui.internal.views.markers.GroupsContribution"
          id="org.eclipse.ui.ide.dynamic1">
    </dynamic>
</menu>

Maybe GroupsContribution could be made API.
