Hi,
I came across the following notation:
MyType1 ::= SEQUENCE {
...,
...}
This seems to be perfectly legal according to X.680 (1997 E) clause 24.1
According to 3.8.29 the 'extension insertion point' is in between the
two ellipsis.
MyType2 ::= SEQUENCE {
...,
alpha INTEGER,
...}
should then be the propper way to extend with a NamedType.
But this does not comply to any of the alternatives in
ComponentTypeLists.
All alternatives in ComponentTypeLists requires a RootComponentTypeList,
which is non-empty.
How do I extend MyType1 according to X.680 (1997 E)?
In the X.680 (1994 E)/Amd.1(1995 E) the notations would have been:
MyType3 ::= SEQUENCE {...}
and extended to:
MyType4 ::= SEQUENCE {..., alpha INTEGER}
Best regards
Egon Andersen
