[ASN.1] Dynamism of ObjectSets

[Ramaswamy]

Hi,     I have the following query regarding ObjectSet. ObjectSet's which are extensible are meant to be dynamic and can expan or contract. Consider the following ASN.1 spec - TidSet-Class1 TYPE-IDENTIFIER ::= { obj1 | obj2 | obj3, ... }   TidSet-Class2 TYPE-IDENTIFIER ::= { obj10 | obj20 | obj30 }   TidSuperSet TYPE-IDENTIFIER ::= { TidSet-Class1 | TidSet-Class2 }       Consider the ObjectSet - TidSuperSet (extensible from TidSet-Class1). There are certain doubts that I have on the dynamism of the ObjectSet. Is it possible to remove the object obj20 from TidSuperSet? If obj1 is removed from TidSet-Class1 is that change reflected in TidSuperSet as well? Can obj1 be removed from TidSuperSet without impact on TidSet-Class1 (from which it derives that object)     My understanding of the above circumstances are as follow. Kindly clarify the same. No, since TidSet-Class2 is not extensbile, as TidSuperSet gets the object from the former. Yes, since obj1 is got by TidSuperSet thru TidSet-Class1, if the same is deleted there it must be here as well. No, similar inference as in point 2.     I am not very confident with the above. Kindly clarify in this regard. Thanking you.   Yours Sincerely Ramaswamy "Any intelligent fool can make things bigger, more complex, and more violent.
