wxb means anything ??

[bombardier]

hello to all:

as I was downloading the A350s I notice alot of camsims planes has wxb after the plane name for example klm wxb and air france wxb and so on. does this mean anything? I know now extra wide body.

its a long shot it might stand for experimental. sorry about the waste of space.

I always presumed he meant extra wide body. He is French Canadian and maybe there wxb means xwb .... or maybe a typo. But I can find no reference to wxb and lots to xwb.
