agreed. It is even simpler for XHTML 2.0, and you do not need the  
DOCTYPE.
One line less. :)

a minimal strictly conforming XHTML 2.0 Document is:

<html xmlns="http://www.w3.org/2002/06/xhtml2/" xml:lang="en">
    <head>
      <title>Tantek's Thoughts</title>

>> Then in the page there are things like
>>
>> <ul class="xoxo facets">
>>    <li><a href="http://technorati.com/profile/tantek"
>> rel="me">Technorati</a></li>
>> </ul>
>>
>> rel="me" has a meaning because of the profile up there.

:) wonderful for all people using class="something" in their pages.  
For backward compatibility, will it be asked to thousand of people to  
fix their class names because it will be interpreted by parsers in  
the wrong way?

because people *can not* do it in most cases. profiles in head  
section. As we say in French, you just made a circular reasoning "Le

	*nobody* … which is a false statement.

I though it was nobody just from above.

So what you are saying is that old browsers now put back the link and  
meta in the head section. Recovering the tag soup. Though it doesn't  
forbid any microformat parsers to analyze the thing in situ in the  
tree. And it is still a benefit for the end user.
