I'm quite new to ASN.1 and have a question related to extension
containers.
Are extension containers used also for backward compatibility ?
For example, regarding the different versions of the GSM MAP standard
(29.002), extension containers seem to be there where an old version of
the standard had a deprecated entry.
V1:
RoutingInfoForSM-Res::= SEQUENCE {
imsi IMSI,
locationInfoWithLMSI [0] LocationInfoWithLMSI,
mwd-Set [2] BOOLEAN OPTIONAL,
...}
V3:
RoutingInfoForSM-Res ::= SEQUENCE {
imsi IMSI,
locationInfoWithLMSI [0] LocationInfoWithLMSI,
extensionContainer [4] ExtensionContainer OPTIONAL,
...}
If I parse a V1 request using a V3 parser, will the extension container
contain the mwd-Set value ?
Thank you in advance,
Marcelo
