[ASN.1] SyntaxList Issue

[Ramaswamy]

Hi,     I have some more clarifications needed w.r.t. clause b) of Sec 10.12 X.681. Pls observe the following ASN.1 spec snippet - ACLASS ::= CLASS {     &Type OPTIONAL,     &valu NULL OPTIONAL } WITH SYNTAX {     [&Type] [&valu] }   aobj ACLASS ::= {     NULL --NULL-- }       In the above e.g. Setting for the 2 OptionalGroup's of the SyntaxList could be misinterpreted if the object is defined as above. In fact the '&valu' could also be a variable type field. In fact if the commented part were removed then the object could be considered unambiguous (though not in context of the above mentioned clause). But the above clearly violates the clause on plausible misinterpretation. In the event of the above being correct, could we come to the conclusion that excepting for the <Type , ValueSet/ObjectSet> and <value, ValueSet/ObjectSet> any other combination of fields that appear from the SyntaxList are invalid. Kindly advise. Thanking you.   Yours Sincerely Ramaswamy "Any intelligent fool can make things bigger, more complex, and more violent.
