[racket-dev] Documentation for 'disappeared-use and 'disappeared-binding

The documentation doesn't appear to explain the meaning of the
'disappeared-use and 'disappeared-binding syntax properties. I've
gathered that Check Syntax looks for them, but I don't know exactly
how it uses them. Do other tools interpret them too?
