Re: Proposition on advanced URL features (Request for comments)

> 1.  The use of ## for special anchors seems reasonable.

Use of more than one "#" character is illegal and not desirable
in the current URI syntax.

We have discussed this same topic many times on the www-talk and uri
lists, and the conclusion is always the same:

   1) fragment identifiers are dependent on the media type of the
      entity retrieved;

   2) fragment identifier syntax should be registered with the media
      type registration;

   3) the "=" character should be used as an indicator for a non-name
      syntax, as in

          #name        (as in current HTML use)
          #id=fred
          #bytes=200-254
          #words=20-24
          #line=4
          #chapter=14
          #page=3

The only thing that prevents this right now is the uncertainty about
how to register this along with a media type, and some volunteer to
look at all the current media types and define a list of appropriate
ones for the initial registry.
