Retired in ISO 639-3: Merge into Miju-Mishmi [mxj] as duplicate
Excerpt from change request document:
It was discovered that the Ethnologue entries for India_Miju Mishmi_mxj and China_Geman Deng_gen are referring to the same language. Gaman Deng is an alternate name for mxj. Kuman is an alternate name for Geman Deng and Kaman is an alternate name for Miju Mishmi. The locations for each language are just across the India/China border from each other. they are both classified in the North Assam branch of the Sino-Tibetan language tree. It is proposed that the name Geman Deng be retained for China (and Myanmar) but assume the same language code as Miju Mishmi, with India being the HUB country for the language.
