In the interest of keeping it light and simple to process, I believe  
it would be enough to make this explicit just before 8.1 by saying  
that any of the two protocols MAY be attempted by an RP (plus fixing  
the fallback from HEAD to GET).

Not "one or more"; GET is REQUIRED, HEAD is OPTIONAL in Yadis. This  
too can be specified inline in sections 8.1 / 8.2.

An RP may choose to only do GET and not care about the more efficient  
(but optional on the server side) HEAD.
