Each mm-backend must have new method `insert-entity'.
+
+** New optional argument of `std11-field-end'
+
+Now `std11-field-end' can accept new optional argument BOUND. Thus
+current interface is:
+
+ std11-field-end (&optional BOUND)
+
+If the optional argument BOUND is specified, it bounds the search; it
+is a buffer position.
