I'm warming to this suggestion. Part of my hesitation was caused by the 
fact that I had misunderstood RFC 5785. I somehow had the impression 
that it discouraged path components beyond the registered name, but that 
impression was false:

    Typically, a registration will reference a specification that defines
    the format and associated media type to be obtained by dereferencing
    the well-known URI.

    It MAY also contain additional information, such as the syntax of
    additional path components, query strings and/or fragment identifiers
    to be appended to the well-known URI, or protocol-specific details
    (e.g., HTTP [RFC2616] method handling).

However, I haven't yet had an opportunity to discuss this in depth with 
my co-author. We'll be back in touch once we've talked about it and 
perhaps discussed it with implementers.
