Ohh, I understand how this tag works, name:ms=xxx should consistent with the name=xxx. However, I can say this tagging is disputed. Sometimes, if a place display their name in English, but also commonly know in Malay (e.g. Serenia City) therefore , although the Malay name should be Bandar Serenia. Should note that Serenia City although is in English, but should be the name, Nor Bandar Serenia. Therefore, it is questionable whether should we really 100% stick to the Osmose validation. Back to topic, it is just a tools. The page also stated.
"Warning 1: Do not map for Osmose, keepright, etc. Only fix real errors which you understand and know how to improve correctly!!!" I don't think not 100% following Osmose is an issue.
