It would be good but i don't know if this is possible. In the Lazarus 
situation, the procedure (event) is added to the public section, so fpc 
can not know if is assigned to a published property or not.

The original idea was a local directive like {$PARAMETER_HINT +/-} or (a 
bit overkill/superfluous) {$IGNORE_PARAMETER [name of parameter]}
