Although that wouldn't necessarily be out of the question either.

I can see several kinds of mappings:

 - Mappings between different-but-semantically-similar DOIs
    - such as mappings between deprecated and replacement DOIs
    - or mappings between DTE DOIs historically constructed separately
      but for the same apps and same roles

   This warrants negotiation only if it is the client that must do the
   mapping.

   I think it will be easier to deploy server-does-mapping.  But I'm not
   sufficiently sure.  To avoid having to add DOI negotiation later, but
   also to avoid having it be a requirement, let's just make DOI
   negotiation an option.

 - Mappings between on-the-wire and server-internal DOIs.

   This is an internal detail warranting no negotiation, of course.
