ACTION-95: use of WCAG2ICT to refer to itself - as "this document" or "WCAG2ICT"

Just put this in the action item and then realized I probably should have
sent it to the list:

I took a pass through the 2nd public draft and the collection of edits for
the 3rd public draft. The current uses of WCAG2ICT as a reference to this
document are limited to the Key Terms, Conformance, glossary, and SC 2.4.5.
(Disclaimer: I didn't get quite all the way through edits for the 3rd
public draft.)

In most cases, it wouldn't make sense to replace WCAG2ICT with "this
document" because there are nearby references to "document" as in "non-web
document". For example, in the conformance section, it states "WCAG2ICT
uses a single document as the "unit of evaluation", as it is the best
analog to a web page." It would be very confusing to say "This document
uses a single document as the ...."

There are some places in the introduction, however, where it might make
sense to replace WCAG2ICT with "this document". I will attempt to make a
specific proposal later today.
