It seems I am the only one who is still against this approach... The proposed encoding is kind of problematic, especially if one would need to add more fields to INFO.ind. And it's still not clear what is the plan for a situation when we would need to send additional SI messages to the PCU, e.g. SI4. Again, why not to introduce a separate PCUIF message type for SI?

PS4, Line 224: 	OCT23  		si1 optional,
This encoding is ambiguous. Imagine that one of the SI kinds is not present for some reason, let's say SI3 is missing. This is possible because those are separate messages on the A-bis/RSL, and the BTS would re-send INFO.ind for each of them. How would you guess on the receive side what is what and where?
