My comments on your note on the numbering of standards.

Hal Keen may have described 802.1 numbering of standards (not PARs) in a
document that he generated some years ago.  Tony Jeffree more recently
incorporated some of Hal's stuff into another document that is on the
802.1 ftp site -- not sure where within the ftp site.

The above is confusing in its description.  An example would help.

I don't know whether you are talking about just the future or both the
past and future, but after much experience with the upper/lower case
scheme, I can only recommend in the STRONGEST terms that you delete item
3).  Using upper/lower case as we have and as you describe above has
resulted in continual confusion.  I have absolutely no reason to believe
that it will not continue to do so in the future.

I don't know what this means.  802.1 has avoided using an upper case
letter for one standard and the same letter in lower case for another
supplement standard.  I can only imagine with horror what would have
happened if we had.

I suggest that you change the first clause above to read: 
    "3.2 -This small and capital letter use has been and continues 
     to be VERY confusing, ..." 
This is the real situation.  Your wording waters down the problem.
