It has been > done above. Other than that, this is This is not setting a flag, it is checking a flag. The w/a only applies to RCS and CCS engines. The above check is for a different w/a. We generally try to keep each w/a separate and discrete. If they start sharing condition terms then things can get broken when the conditions for one w/a need to be changed and the code has to be untangled.
