+.B \-M
+Allows the use of the value
+.B omit
+in template lists and complemented template lists (legacy behavior).
+If set, an omitted field will match a template list, if the value
+.B omit
+appears in the list, and it will match a complemented template list, if
+.B omit
+is not in the list (the
+.B ifpresent
+attribute can still be used for matching omitted fields). This also affects the
+.B ispresent
+operation and the
+.B present
+template restriction accordingly.
