This implementation looks good to me. Thanks for adding tests 😸
@jfirebaugh seems like you were on board with adding this functionality in #1485 – does this work for you?

I think it would be a good idea to explain here that this is added specifically to the AttributionControl

The style-spec is platform independent so I'd say best not to refer to the platform specific AttributionControl. What do you think?
That said, it should be consistent with the other sources that accept an attribution option like vector, raster and raster-dem sources. eg. https://www.mapbox.com/mapbox-gl-js/style-spec/#sources-vector-attribution so any change in this wording should apply to all the others too.

ah good point. 👍 to keep as is

should we validate that options.attribution is a non-empty string?

The attribution option is optional so is that needed? If the attribution option isn't provided, or if it's an empty string it won't set any attribution on the source and the AttributionControl won't add any attribution for it.

sorry I was unclear– I was thinking of validating that it is a string (as opposed to another type) and that its "non-empty." I was thinking about just white space, not a true nonempty which would be truthy). the first part is already happening in the style validation code which I forgot, and I'm not sure its worth worrying about the white space case after all because we don't do that for any other style spec values. sorry for confusion!

That's right the style validation already spews out an error for a non-string value (handy if someone uses something like true by mistake. (Thanks for pointing that out by the way, I didn't actually realise it did that already)
As for white space, I'd say we allow it, if someone wants an attribution of "" or " " we should just comply.

@mollymerp not sure if this slipped through the cracks, or it needed further changes? Thanks! |

Launch Checklist
adds support for custom attribution strings in GeoJSON sources. This implements the latter part of the discussion of #1485, but could be used as a workaround for the original issue by using a dummy GeoJSON source.
I think to close #1485 we would still need to allow custom attribution strings passed directly to the AttributionControl not attached to any source.
The Vector and Raster sources set their attribution properties via the shared TileJSON code, but since GeoJSON is loaded directly without a TileJSON, they need to be handled separately in the GeoJSON Source code.
