+ * always appear to the client to be the default value for its type.
+ *
+ * If OVSDB_IDL_MONITOR is set, then the column is replicated. Its value will
+ * reflect the value in the database. If OVSDB_IDL_ALERT is also set, then
+ * ovsdb_idl_run() will return "true", and the value returned by
+ * ovsdb_idl_get_seqno() will change, when the column's value changes.
+ *
+ * The possible mode combinations are:
+ *
+ * - 0, for a column that a client doesn't care about.
+ *
+ * - (OVSDB_IDL_MONITOR | OVSDB_IDL_ALERT), for a column that a client wants
+ * to track and possibly update.
+ *
+ * - OVSDB_IDL_MONITOR, for columns that a client treats as "write-only",
+ * that is, it updates them but doesn't want to get alerted about its own
+ * updates. It also won't be alerted about other clients' updates, so this
+ * is suitable only for use by a client that "owns" a particular column.
+ *
+ * - OVDSB_IDL_ALERT without OVSDB_IDL_MONITOR is not valid.
