You would still have to identify what service you want your data to be used
with. Are you thinking of embedding a service "code" of some kind in the
data itself?

In other words, you would need both. Conceptually, you can combine the two
"approaches" as:

<getFlights>
    <itinerary>
        ...
    </itinerary>
</getFlights>
