ATSEEL and AAASS have not yet officially agreed upon a recognized standard set of keyboard layouts. However, ATSEEL's Ad Hoc Committee on Standardization of Computer Keyboards for Cyrillic does have a suggestion for keyboard layout usage.
Apple has included as shareware on the CD, Matvey Palchuk's keyboard layout which is based on the work of ATSEEL's Ad Hoc Committee. Since, there was no agreed upon standard at the time Apple's Cyrillic Language Kit was released, it was decided that this was the most appropriate approach for Apple to take.
