Excerpt from change request document:
Kenyah, Mahakam is a vague name associated mainly to toponym or ethnonym of some Kenyah groups. The name was proposed by Wurm and Hattori (1981) mainly based on what Soriente (2005:19) calls "superficial analysis focusing on geographic and administrative boundaries". Using the means of comparative linguistics methodology, Soriente (2005) is able to re-classify the variants of Kenyah.
[RA comment: This Kenyah language is being requested to be retired as "non-existent" because it is not clear to which of the two Kenyah languages (one existing, but expanded, and the other newly defined) the former geographically specified language would belong. See requests 2007-245 and 2007-246.]
