alert: authoritative metadata discussion on www-talk

Just a heads-up for those who care:

On www-talk now there's a discussion of site metadata and whether it
can be considered authoritative, and over what. This relates to the
TAG's work in the area of naming authority (URI ownership) and
authoritative metadata. It also connects to the recent flurry of
activity on the Link: header, which also has authority issues. Anyone
who cares about this should probably take a look at the active thread
on www-talk. Following is a link to one of the more recent messages:

I'm not proposing to discuss (or not discuss) the issue here.
