I have just posted version 1.6 of my proposal on mapping disputed
boundaries. It tightens the definition of the "controlled by" tag in an
effort to improve verifiability.

*Changelog*

   - *Version 1.6*
      - Defining terms for "controlled_by" tag to improve verifiability.
   - *Version 1.5.1*
      - Adding role de_facto for boundary relations in Conflict Areas.
   - *Version 1.5*
      - Eliminating Zones of Control as concept.
         - Permitting claimed_by and controlled_by tags to be placed
         directly on administrative boundary relations, eliminating those (now
         redundant) Zones of Control
         - Other Zones of Control become Boundary Claim relations.
      - *Version 1.4.2*
      - Changing Crimea example to conform to current administrative
      boundary.
   - *Version 1.4.1*
      - Changing "all" keyword to a list for the value of the
      "controlled_by" tag.
      - Adding "UN" as a special value for the "controlled_by" tag.
   - *Version 1.4*
      - Using maritime boundaries instead of land boundaries
      - Eliminating redundant or unneeded relations:
         - De facto relation is eliminated; it is now the same as the
         existing administrative boundary
         - Minimal boundary is eliminated; it is now a Zone of Control with
         role "undisputed" in Master Claim
         - Master Claims and Zones of Control are eliminated when not
         needed, such as for countries with no disputes
         - Conflict Areas are explicitly made optional
      - Roles in Master Claim now differentiate how claimant and zone are
      related: undisputed, joint, de facto, claimed
      - Describing administered territories
      - Adding how to change the criteria for the List of Claiming Entities
   - *Version 1.3*
      - Possible extensions page added
      - Flattening the hierarchy by removing Disputed and Undisputed Areas
      - Three Boundary Relations: de facto, master, minimal
      - All Zones of Control have the role zone in the three Boundary
      Relations
      - Eliminating Lines of Control
      - Country code tag introduced
   - *Version 1.2*
      - Removing "according_to" tags
      - Adding Zones of Control and Lines of Control
      - Adding Disputed Areas and Undisputed Areas
      - Using type=land_area + land_area=administrative
      - Full country relations are no longer members of each other.
   - *Version 1.1*
      - Adding "according_to" tag for relations
   - *Version 1.0*
      - Initial proposal.
      - Land-based borders only; no maritime claims.
      - De facto and claimed borders and roles
      - List of Claiming Entities
      - OSM-designated borders
      - Claimed border relation becomes a member of the De Facto border
      relation, and vice versa

I welcome feedback (public or private) on the new Resolution Period idea
for the "controlled by" tag -- the notion itself, and the length of the
period.

I've archived some of the comments that are no longer applicable.
