037 * <li>
038 * To delete tag(s) <b>to the given resource

042 * a parameter of type {@link TagList} which will contain the list of tags
043 * to be deleted.
044 * Note that for a
045 * server implementation, the {@link #type()} annotation is optional if the
046 * method is defined in a <a href=

052 * attribute specifying the resource type, and the method should have a
