The simple solution to integrate your requested feature into XHTML2 
without ditching the current <link/> mechanism would be this. Define a 
"sitemap" value for the rel attribute, so that somewhere in the page head 
there would be this:

<link rel="sitemap" href="map.xhtml" type="application/xhtml+xml" />

or even somewhere in the page body there could be:

<a rel="sitemap" href="map.xhtml" type="application/xhtml+xml">Site 

As part of the definition for the sitemap relation, it should be specified 
that the linked page should have the following format. It should contain 
the elements specified below and nothing else.

    <title>Title Of The Whole Site</title>
    <meta name="Description" content="description of whole site" />
    <meta name="Keywords" content="keywords, for, whole, site" />
    (maybe a few links like made, copyright, etc. links like next and 
    previous probably wouldn't make sense as this information should 
    apply to the whole site, not just the one page!)
      (Appropriate children)

Any user agent that supported XHTML2 links would thus automatically 
support sitemap without any extra work, as it would just be a regular 
XHTML2 page. However, browsers could build in special support for sitemap 
by automatically downloading the site map for any page that referenced it 
and displaying it in a Mozilla style side bar, or using the included 
navigation list to create a drop down menu.

Because lack of consistant navigation is one of the most common complaints 
from beginner web users. By letting the browser/user have total control 
over how <link/> elements are presented, you solve this problem.
