Nominatim Usage Policy: clarify attribution requirement

[mashedkeyboard]

Hi folks,

The Nominatim Usage Policy says one of the requirements for Nominatim usage is

Clearly display attribution as suitable for your medium.

However, it's not clear whether this ought to be attribution to Nominatim in some way, or whether it ought to be the same attribution used for all other OpenStreetMap stuff (i.e. as per the OSM copyright page). It seems reasonable to assume it's the latter, as the former is clearly a product of data from the latter, and indeed this is how I've seen it used around the Internet. I think it's probably worth just clarifying that in the usage policy, because the existing wording is slightly ambiguous on that front.

If my assumption there is incorrect, it definitely ought to be specified, because that seems like a change to how most people have been interpreting it!

Cheers,

Curtis
