Draft ZIPs
----------

These are works-in-progress that have been assigned ZIP numbers. These will
eventually become either Proposed (and thus Released), or one of Withdrawn,
Rejected, or Obsolete.

In some cases a ZIP number is reserved by the ZIP Editors before a draft is
written.

Drafts without assigned ZIP numbers
-----------------------------------

These are works-in-progress, and may never be assigned ZIP numbers if their
ideas become obsoleted or abandoned. Do not assume that these drafts will exist
in perpetuity; instead assume that they will either move to a numbered ZIP, or
be deleted.
