For HTML resources, the obvious thing to use would be link
relations[1,2] (using the <link> tag).  The Link HTTP header has
sometimes been used to represent the same semantics for non-HTML
resources.  Existing relations that are close in meaning:

  - "alternate" seems similar, though it's notionally for referring to
    alternate _representations_ rather than alternate _locations_.
    (The exact distinction isn't entirely clear, but the intent seems
    to exclude cases like this.)

  - "canonical" asserts a "preferred" version/location, which isn't
    quite what's wanted here.  A weaker form of "canonical" would be
    useful.

  - "duplicate" asserts that the representations are exactly identical,
    which as the IANA listing describes makes no sense for dynamic
    content, so that's not directly useful here.

Out of curiosity, has this been taken up with any of the relevant
working groups?
