Latest revisions:

  - the language extension proposal is included, importing a slightly
    edited version of Malcolm's original proposal.  The section on
    'implicit as' is placed under a "possible extension" section
    heading, as we haven't come to a conclusion on this yet.

  - Note proposal to rename Org to Contrib

  - Add hierarchy design guidelines

  - Rename NHC to Nhc consistently

  - Elaborate on what we mean by "approved extensions" in the
    portability section.
