I'm not following you here. 'T < V < L' works well in Mark's and my scheme for the most generic form of Korean syllables, 'L+V+T*' as far as South Korean collation rules are concerned. > The Vs at two radically different positions in the table > is for different positions of the V in a syllable; V < L is for first V in > a syllable, T < V is for non-first Vs in a syllable.

Indeed. However, I'm wondering if avoiding TERM is a better trade-off than avoiding seemingly more complex(than Mark's and mine) scheme of yours that also requires pre-handling. Could you give me some rationale behind your preferring yours to the other? Is it because it's better suited to tailoring for North Korean? I haven't given much thought to North Korean collation rules recently (at the moment, I have to look them up again to refresh my memory.) Jungshik
