Xfn on the Google Reader shared items page

I recently went to the Google Reader shared items page to check the microformat.Source codeI want to see how Google works. There is a connection to the Google profile on the page. Interestingly, the link is placed in

<LinkREL="Me"Href= "Http://www.google.com/profiles/113557210616935738114">

although the xfn specification only specifies the use of rel =" Me ", but generally placed in . It may be because the profile is generated by calling JS on the shared Item Page. There is no way to add Rel. And the page is html4, not HTML, as the link above is not well-formatted XML.

I don't know what the impact of writing on the microformat parser will be.Google's social gragh is based on xfn, So Google Reader's outbound information is not used.
