You misunderstand. I didn't want to suggest it for browsers, but for
site developers. Over time, as people change their Websites to use
such structured fragment URIs, we may be able to bring it into the
browser, but I don't expect it to be before another 5-10 years. Some
sites already use this kind of markup (see YouTube for example). It
would be nice to recommend a common naming scheme for all sites. They
don't have to follow, but more is done today by convention than by
standardisation.

Seems we missed that discussion at the F2F. :-)

Cheers,
Silvia.
