Conrad,
thanks for your reply but I don't understand why this :
UDPTLPacket::=SEQUENCE
{
seq-number INTEGER(0..65535),
primary-ifp-packet TYPE-IDENTIFIER.&Type (IFPPacket),
.. -- other fields
}
is not the same as
UDPTLPacket::=SEQUENCE
{
seq-number INTEGER(0..65535),
primary-ifp-packet IFPPacket,
.. -- other fields
}
and why using the constrained object class field instead of the type itself?
thanks
augustin
