[osis-core] unbalanced <q> elements

[Chris Little]

I'm marking up the TEV and could use some advice.

We've got <q/> for marking balanced quotations.  And we've got 
<milestone type="cQuote"/> for marking continuation quotes.

1) If I'm marking quotation levels, how should I indicate this on 
continuation quote milestones?  Should they be linked with their <q/> 
parent elements (perhaps with a new cID attribute, similar to the sID & 
eID attributes)?

2) If I have unbalanced quotes that are not continuation quotes, how 
should I mark them?  Perhaps with a <q/> that has an sID or eID but 
without a matching <q/> with the same value?  Specifically, I have some 
close quotation marks inside of notes that lack matching open quotation 
marks.
