So far I have used denomination=orthodox but there is a tag denomination=serbian_orthodox listed here http://wiki.openstreetmap.org/wiki/Key:denomination
The value serbian_orthodox is not used very much, only 126x times, including many times abroad.

I have zero knowledge about the difference between orthodox and serbian_orthodox. Is there a need for changing all “orthodox” in Serbia to serbian_orthodox?
If there are other orthodox churches denominate then there is no reason not to use serbian_ortofox. In Serbia it is not that obvious as there are only Serbian orthodox churches. Abroad there are others (Russian, Greek…) and there is need to make difference.
@Pedja
Not all Orthodox churches in Serbia are Serbian Orthodox. We have e.g. Russian, Romanian, and other communites.
@SunCobalt
If it is known, a specific denomination should be used, as various Orthodox churches, although related, are autonomous.
There is no question then that serbian_orthodoh denomination is needed along others an that should be set for all such churches.
