In fact, there is one more sequence to consider. Kartika in Windows follows
<NA, VIRAMA, ZWJ, RRA> for NTA. However, the existing data in that sequence
is quite less.

In case, Chillus standard is asking display software to be prepared for
data in both sequences. I agree, it could document NTA's legacy Vs standard
sequences, likewise.
