I don’t disagree, really, since there’s a practical consideration here
and precedent from other languages. Compiled C programs don’t have
access to their source code, etc.

But note that RFC 3986 does *explicitly* license the “same document
reference” in section 4.4:

  When a same-document reference is dereferenced for a retrieval action,
  the target of that reference is defined to be within the same entity
  (representation, document, or message) as the reference; therefore, a
  dereference should not result in a new retrieval action.

It isn’t a dreadful hack that someone has discovered just happens to
work, it’s a dreadful hack predicated on an aspect of web architecture
that seemed reasonably easy to support in 1.0 and which is not easy to
support in 3.0.

                                        Be seeing you,
                                          norm
