5 abvs

Note: Noto Serif Kannada has some abvs-like substituations in pres lookup 14 (via single-sub lookup 23), but I have not yet figured out whether they are, linguistically speaking, actually above-base features. Thus, they are included here, but might not be used in the shaping document.

5 blws

Note: Note Serif Kannada has some blws-like substitutions in pres lookup 12 (via contextual chaining lookups 7 and 8 (via single-sub lookups 19 and 20)), but I have not yet figured out whether they are, linguistically speaking, actually above-base features. Thus, they are included here, but might not be used in the shaping document.

5 psts

Note: Noto Serif Kannada has some psts-like lookups in pres lookup 12 (via single-sub lookup 21 and 22 (via contextual chaining lookup 9 and 10)), but I have not yet figured out whether they are, linguistically speaking, actually post-base features. Thus, they are included here, but might not be used in the shaping document.
