For review: Rules for Simple Placement of Japanese Ruby

In preparation for publication as a Working Group Note, we are seeking 
wide review of the document Rules for Simple Placement of Japanese Ruby 
<https://www.w3.org/TR/2020/WD-simple-ruby-20200609/>. We are looking 
for comments *by Friday 26 July*.

The Japanese layout requirements document describes some complex aspects 
of ruby handling, and frequently offers alternative possible approaches. 
This document provides a single, simple set of rules for placement of 
Ruby text in Japanese typography which can be used as a minimal baseline 
by implementers and spec developers.

Please send any comments as github issues 
<https://github.com/w3c/simple-ruby/issues/>.

thank you.
