Ian,

Indeed, the URI RFC states that fragment identifiers are defined on a
per-MIME-type basis.

We have made an analysis to find out if there are any media types registered
with IANA that contain information about how fragment/anchor identifiers are
constructed for use in conjunction with this media type. as defined in RFC4288
(Media Type Specifications and Registration Procedures). As a matter of fact,
almost none of the media type RFC states something about fragments. You can
read about this analysis at
http://www.w3.org/2008/WebVideo/Fragments/wiki/MediaTypeReview

Note that we have also an open issue about this in our tracker:
http://www.w3.org/2008/WebVideo/Fragments/tracker/issues/13

Having said this, the Media Fragment specification contains currently a note
for implementers, read
http://www.w3.org/2008/WebVideo/Fragments/WD-media-fragments-spec/#implementor-notes
that states how a UA (e.g. an HTML5 compliant browser) could render/display a
media fragment. The Working Group is currently discussing whether we should
describe or mandate particular behaviors depending on the UA. Some followers
(of both groups) have expressed strong views on what a browser should do, such
as highlighting or cropping an image in case of a spatial media fragment.
Another possibility is to have a new attribute in the media element that
indicate what a browser should do. This bug has been entered to discuss and
resolve this issue.
