[clreq] Can long 'ruby text' overlap non-Hanzi characters, and how much?

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

== Can long 'ruby text' overlap non-Hanzi characters, and how much? ==
3.3.4.1 Basic Requirements 
https://w3c.github.io/clreq/#h-basic-requirements

>  5. Annotations are allowed to extend to the top of adjacent base 
text as long as the minimum spacing is ensured. 

This doesn't put any restrictions on
a. the type of characters that can be overhung
b. the distance the overhang can travel

I wondered about (a) because the TTML spec currently says that 
overhang is only allowed for hanzi. Is that correct?  Are punctation 
marks or Latin base text excluded?

In jLReq the maximum overhang is usually the width of one ruby 
character.  Are there any similar guidelines we should add to cLReq?
