[ISSUE-132] - New edits for LQI

Hi all,

Attached are the latest versions of the LQI sections, including a new, non-normative appendix. For the first two files, Word track changes indicate what has changed. For the third, all of the content is new except for the part with changes tracked, which was moved from the main description.

Please send any feedback by September 3, if possible, as that will give me two days to work it in before handing off for implementation in the spec.
