Retired in ISO 639-3: Merge into Awngi [awn]
Excerpt from change request document:
The language code element for Kunfal [xuf] should be retired, and Kunfal should be merged with Awngi [awn]. Kunfal has been shown to be a dialect of Awngi, according to the results of two survey trips undertaken by Andreas Joswig, Hussein Mohammed and Ryan Boone in 2005 (to be published). Comprehension testing results and interview data regarding language attitude and identity all support this conclusion. Speakers of the Kunfal variety can understand Awngi texts with no problem and identify it as their own language.
