Opt Subject: Feedback on PRI 555

I write and maintain unicode_string, a conformant implementation of UAX #14 and UAX #29 written in the Elixir 
language.

This feedback comes from having implemented the proposal against Unicode Version 18.0 data, comparing it directly 
with my existing hand-written implementation, and then adopting it: the published tables drive all four break types 
in the released version.

Please find attached a PDF of my feedback, and a link to the same document in the github repo.

Thanks for the opportunity to contribute,

Regards, —Kip
