Summary:  Ready with nits.

Comments: there are some editorial nits, many summarized below.  There are
several cases where an article - i.e., "the", "an", etc. is missing.   I
believe these can be fixed in AUTH48 and I imagine the RFC editor will
catch them. But, if the doc needs any other updates, it would be good to
make these fixes at the same time.
