Not to my knowledge.  At least RFC2518 doesn't mention one, and I
haven't met a 'common' one.  Clients / server frequently implement
something custom for that [sadly].  Which why I'm happy to add support
for that property to my server.   But there is no documentation if it
should be YES/NO, True/False, 0/1, etc...
