Hi Pascal,

I'm not a BER or PER guru but:

- I need to decode checkIMEIs coming from real network.
- I don't know if these checkIMEIs are really standard or extension by Ericsson
- I tried, with external help, to manage that unhandled tags changing current
ASN.1 definition a lot of times.
- The patch is compiling and working to me on Linux and below is the print as
text output.

If you know a better solution to adhere to ASN.1/BER/PER/3GPP specifications
would be great, but it's really useful for my team to decode that tags,

thank you
Fabio
