Remarks

IModifyTask is an indicator interface used to determine if a particular edit task is the Modify Feature task in the Editor.  The preferred approach is to ask the edit task for its unique name using IEditTask::UniqueName.  In the case of the Modify Feature task, its unique name is "GarciaUI_ModifyFeatureTask".
