I imagined the above 2 would be nested.

The Application Profile would add profiling (MUST send this option, MUST 
NOT send this option, this option defaults to X, the server is allowed to 
do either X or Y, etc.).

Then the Implicit Parameters would further profile anything the Application 
Profile left open.  I.e. the Application Profile would say: server must do 
either X or Y.  A particular server would choose to do Y, and that would be 
an "Implicit Parameter".

The idea is there's a family resemblance among servers that implement the 
same Application Profile, but the Application Profile leaves some wiggle 
room for each individual server to do its own thing.
