Retired in ISO 639-3: Merge into Kipfokomo (Pokomo) [pkb]
Excerpt from change request document:
The current name Pokomo does not reflect the language name according to the speech community. They say that their language name is Kipfokomo The "Upper" distinction is no longer needed, as this proposal also recommends the merging of Lower Pokomo [poj] with Upper Pokomo to have a single code element encompassing all of Kipfokomo, nee "Pokomo".
The current distinction between Upper Pokomo and Lower Pokomo is not so much a matter of linguistic intelligibility as it is of other distinctions. On linguistic grounds (including use of literature), these should be considered one language.
