It seems to be used as the name of the reservation action?!
Are you consuming this in PBI in that format?
I was wondering whether I should, currently I do. "Prenota un tavolo" might not mean much to a non-Italian, though.
However, I think another consumer could just check for "ReservationAction" and ignore the name.
It surely tries saving me from walking back the chain to see "ok, this is a reservation action for... a restaurant" and then show the appropriate "reserve a table" text.
