We briefly discussed the history of this proposal. There have been two disagreeing factions: one that preferred explicitly coded subscript consonants (called the subscript model), and one which preferred the current UCS model which uses virama to create consonant conjuncts (called the virama model). The main benefit of the subscript model was thought to be in improving the user interface. The main benefit of the virama model was ease of implementation as it is a well-known model. During the discussion, we came to the conclusion that the user interface could be managed equally well by either model. We also ided that the subscript could prove to be too inflexible for unusual conjuncts whereas the virama model is more productive. Based on these points, we ided to endorse the virama model, with characters encoded in natural Khmer order. We also ided to unify one character from Maurice Bauhahn's most recent proposal, the KHMER SUBSTITUTION SIGN with U+5CC DOTTED CIRCLE. Maurice Bauhahn agreed to provide an improved list of character names. We wish to improve the transliteration spellings. Burmese. The basic proposal was agreed to easily; it is a virama model. The main items of discussion were character ordering, initial vowels, and subscript YA, RA, VA, HA letters. We ided to encode characters in natural Burmese order. Lee Collins had proposed to delete eight vowels from N15, but after discussion, we dccided to retain the six vowels used in Pali and Sanskrit. The four subscript letters proposed by Lee Collins were not required when using the virama model, so they were not accepted. The consensus of the group was to progress both proposals as PDAMS.
