[issue-132] clarifications of LQI section + types: edits done, please review (and one question)

Hi all,

the edits (also the HTML5 reference update) are now done, see

http://www.w3.org/International/multilingualweb/lt/drafts/its20/its20.html#revisionlog

Please have a look and provide comments in this thread. I have one question:

" Additional guidance on this project may be found at [Multidimensional 
Quality Metrics]."

We don't have a reference to MQM yet - Arle, can you provide one? A 
conference paper would be fine too.

Best,

Felix
