Update: I had complained that hash URIs limit the media type that can be
used to serve the associated URI declaration, because the meaning of the
fragment identifier depends on the media type returned by the racine,
and therefore if one were using a hash URI to identify a person, for
example, then one could not serve HTML from the racine, because the HTML
media type says that the fragment identifies an element within the
returned document.  However, Leo, Richard and Max's "Cool URIs" document

has suggested a hash/303 hybrid approach that avoids this limitation by
having the racine 303-redirect to the URI declaration, which can then be
served using any media type.  Therefore, my complaint about that
limitation of hash URIs should be withdrawn.  This media type dependency
is not an *inherent* limitation of hash URIs.  Rather, it is a
limitation of hash URIs only when the racine directly serves
