  | RuyiNetHttpStatusPRECONDITION_REQUIRED Field | 
 [This is preliminary documentation and is subject to change.]
            The origin server requires the request to be conditional. Intended to
            prevent the 'lost update' problem, where a client GETs a resource's state,
            modifies it, and PUTs it back to the server, when meanwhile a third party
            has modified the state on the server, leading to a conflict.
