To go all the way to Xkb, even three-set keyboard array has to be
modified a little because some clusters of vowels and consonants
are not assigned separate keys, but have to be entered by a sequence
of keys assigned to basic/simple vowels and consonants. Alternatively,
programs have to be modified to truly support 'L+V+T*' model of Hangul
syllables as stipulated in TUS 3.0. p. 53.

You almost got it right except that IEung ('ㅇ') is NULL at the
syllable onset position (i.e. it's a place holder for syllables that
begin with a vowel and does not appear in Latin transliteration). IEung
is not NULL at the syllable coda-position but corresponds to [ng] (IPA :
[ŋ] ) as in 'young'. To put in your way, V-C2 syllable is always written
as IEung-V-C2 with IEung having no phonetic value. Here I assumed
we're not talking about the orthography of the 15th century ;-)
