If the decision can be taken today or tomorrow, then I do not see any problem with Tuesday. Implementing the decision is a simple editorial step, that can be done very quickly

There are two possibilities here, I am not sure which of the two you propose:

a) you propose to add something on @about="" on the root but no other modification; in this case the modification is superfluous. 
b) you propose to add something on @about and _remove_ the reference to <head> and <body>. In that case we create a backward compatibility issue. Indeed:

<html rel="q:r" resource="http://manu.com">
  <head>
    <meta property="a:b">aaaa</meta>
  </head>
</html> 

would, under the new rules, produce:

<base> q:r <http://manu.com> .
<http://manu.com> a:b "aaaa".

whereas, in RDFa 1.0, because there is an implicit about on the head, this would produce

<base> a:b "aaaa" .

Oops:-)

If the current text remains unchanged than, in RDFa 1.1, the triples to be produced would become:

<base> q:r <http://manu.com> .
<base> a:b "aaaa".

which is all right with backward compatibility, too.

As a consequence, my proposal is _not_ to touch the XHTML+RDFa document. It is ugly, but an unimportant corner case in practice.

Unfortunately, I take a flight early tomorrow morning. I *might* look at my mail later today.
