DIX/SXIP delegation tag, HTML LINK rel, and profiles

John, Lisa,

It was good to see you at the W3C authorization workshop this week.
   http://www.w3.org/2005/Security/usability-ws/program
I'm pretty excited about DIX/SXIP and related web-like authorization  
mechanisms,
but I don't think I can swing a trip to Dallas for the BOF next week.
   http://www3.ietf.org/proceedings/06mar/agenda/dix.html

It's great that DIX/SXIP uses URIs for naming, and that it delegates  
via DNS.

But the way it's done in section 5.10.3.2. Delegation Tag
of http://dixs.org/index.php/Draft-merrells-dix-01.txt ...
    <LINK REL="dix:/homesite" HREF="http://www.sxip.net/homesite"/>

... isn't using HTML as designed and specified.

In HTML 4, we added a profile attribute to the head element for this  
purpose.
   section 7.4.4.3 Meta data profiles
    
http://www.w3.org/TR/1999/REC-html401-19991224/struct/global.html#h 
-7.4.4.3

So I suggest in stead:

   <head profile="http://dixs.org/terms#">
    <link rel="homesite" href="http://www.sxip.net/homesite"/>

(more on dix: vs dixs.org separately.)

I note the draft doesn't include a normative reference to any HTML  
specifications. Please
add one.

Also, the proposed charter ( http://dixs.org/index.php/DIX_Charter )  
does not make
any connection to HTML. Please add something to note that use of HTML  
syntax,
especially extensibility mechanisms like rel and profile, is in scope,  
in order to attract
review from relevant experts.
