[ttml2] Meaning of 'glyph area descendant'

r12a has just created a new issue for https://github.com/w3c/ttml2:

== Meaning of 'glyph area descendant' ==
[This was a quick query by email, but it is developing into a thread, 
so i'm copying the discussion here for ongoing discussion.]

my original question:
I'm working on review comments for the ruby section, but i'm a bit 
stuck because i don't understand the meaning of the term 'glyph area 
descendant', and i don't see it described anywhere.  Could one of you 
explain what that is?  I think it will be important to understand it 
in order to assess the ruby section.
