+.IP "5.1. Notation"
+For <condition>, RFC 7047 only allows the use of \fB!=\fR, \fB==\fR,
+\fBincludes\fR, and \fBexcludes\fR operators with set types.  Open
+vSwitch 2.4 and later extend <condition> to allow the use of \fB<\fR,
+\fB<=\fR, \fB>=\fR, and \fB>\fR operators with columns with type ``set
+of 0 or 1 integer'' and ``set of 0 or 1 real''.  These conditions
+evaluate to false when the column is empty, and otherwise as described
+in RFC 7047 for integer and real types.
