Problem description
Make response properties "latestSimChange" and "swapped" required since they will always be returned

Hello @fernandopradocabrillo
Are we sure for latestSimChange as this is not the outcome of #16 ?

My apologies if I missed a conversation within the team to agreed on this. Not a blocker for me but wanting to be sure we have agreement.

Hi @bigludo7
I assume this was the agreed outcome since we haven't had any new update and Toyeeb's summary pointed in that direction. I missed that meeting but there seemed to be a consensus.
From TEF we have actually implement in this direction using the null as preferred option.

Hello @fernandopradocabrillo
But option 2 of the #16 is:

# 2 - an empty body returned because latestSimChange is an optional attribute
{

}

I'm fine to remove this option but probably let's wait a formal discussion in next meeting - wdyt?

Hello @bigludo7
Sure, let's discuss on the next meeting. Maybe I was too fast in assuming the outcome, the empty body option is feasable for us too, I just thought it was out of the table.
