Comment: para 1 says "as a result authoring tools WILL play an important role ..." - implying a future role for authoring at some time in the future. Authoring tolls paly an important role NOW.
change wording to "as a result authoring tools play an important role ..."
This was meant to refer to the future when WCAG 2.0 was out. But this wording should be written to match that future. The draft has been updated as proposed. Good catch.
