+ // have on the local state in a customized fashion. If this
+ // field is not stated, it means we don't care about it.

+ // same tag becomes an ordering point
+
+ @OPClear: condition // If the specified condition satisfied, all the
+ // ordering points and potential ordering points will be
+ // cleared
+
+ @OPClearDefine: condition // If the specified condition satisfied, all the
+ // ordering points and potential ordering points will
+ // be cleared, and the atomic operation right before
+ // becomes an ordering point. This is a syntax sugar
+ // as the combination of an "OPClear" and "OPDefine"
+ // statement
