GNAT 3.10: Decriminators for tasks ?

[boavista@berlin.snafu.de (Michael Erdmann)]

Hi

I like to do something like this:

    TASK TYPE  OS_Application( p : Application_Class );

    TASK BODY OS_Application( p : Application_Class ) IS
    BEGIN
          ......
    END OS_Applications ; 

I allways get the message "descriminant part not allowed in task body", 
but found some examples like this in the Ada 95 rationale section about
tasks. What is wrong ??
