     * The UI-element which triggers 'deletion' (either soft or hard).
     * 
     * - A 'hard deletion' is if the point is actually deleted from the OSM database
     * - A 'soft deletion' is if the point is not deleted, but the tagging is modified which will result in the point not being picked up by the filters anymore.
     *    Apart having needing theme-specific tags added (which must be supplied by the theme creator), fixme='marked for deletion' will be added too 
     * 
     * A deletion is only possible if the user is logged in.
     * A soft deletion is only possible if tags are provided
     * A hard deletion is only possible if the user has sufficient rigts
     * 
     * If no deletion is possible at all, the delete button will not be shown - but a reason will be shown instead.
     * 
     * @param id: The id of the element to remove
     * @param softDeletionTags: the tags to apply if the user doesn't have permission to delete, e.g. 'disused:amenity=public_bookcase', 'amenity='. After applying, the element should not be picked up on the map anymore. If undefined, the wizard will only show up if the point can be (hard) deleted
