Re: Reviving HTTP Header Linking: Some code and use-cases

I've submitted a draft-01 (perhaps against my best judgement; this  
discussion is rapidly consuming the mailing list...), which should  
appear shortly. In the meantime, it's available at <http://www.mnot.net/drafts/draft-nottingham-http-link-header-01.txt 
 >.

It is in no way a finished product; it's just a straw-man that tries  
to cover the issues, so it's easier to appreciate what they are (even  
if we don't go in this direction).

Cheers,
