Oh, thanks! It could be a good idea to check where and by whom it was added, and check if it could or should be cr-Latn.

I actually also saw cr-SRO in the name:<lang> list, per Wikipedia I'm guessing this is "Standard Roman Orthography" - wonder if this could be retagged to cr-Latn as well, or cr-SRO should be added here?

I see you used cr-Latn in your issue osmus/tileservice#20. Does that mean only valid ISO codes can or should be be used in the tileservice?
