Atom Bidi Update

[James M Snell <jasnell@xxxxxxxxx>]

This draft defines the dir attribute as part of the Atom namespace and
adds it to the atomCommonsAttributes pattern.  All other details remain
the same.

Example:

  <feed xmlns="http://www.w3.org/2005/Atom"; dir="rtl">
    ...
  </feed>

As always, comments welcome and encouraged.
