     They didn't say that you couldn't do so, rather that you shouldn't 
ever need to do so. It was my understanding that SDP was left in place 
to allow users to tap into experimental features before they became 
standard (similar to prefixed CSS entries). My argument was that we 
would be better off introducing prefixed Constraints or 
implementation-specific Constraint methods rather than exposing SDP.

     Cullen and Adam, feel free to speak up if I misinterpreted what you 
said.
