Hi @maxl2287,
To ensure that we only have one item in the array, shouldn't we also set maxItems=1

Hi @maxl2287, To ensure that we only have one item in the array, shouldn't we also set maxItems=1

That is a discussion we are having for the Geofencing API, and there consensus is that it makes sense to add the maximum as well, for APIs aligned with this version of Commonalities. In future releases, if several events per subscription are allowed, we can remove the limit.

@jlurien @PedroDiez @patrice-conil:

I have now also set the maxItems: 1, so that we enforce one subscription-type within a request at least for this upcoming meta-release v0.4.0.

To me is fine if we have consensus on it @patrice-conil, @shilpa-padgaonkar, @rartych (giving LGTM in advance)
