Deletes a model element indicated by element ID supplied as a parameter. With process steps and stores it is possible to delete also only a single instance of the element. Note that at the moment the only supported way to get an element's ID is to use XML Export and convert the XML ID (e.g. 'PG_PS123456') to Long.
