<p>A global distributed Social Web requires that each person be able to control their identity, that this identity be linkable across sites - placing each person in a Web of relationships - and that it be possible to authenticate globally with such identities. By making distributed authentication easy one can allow everybody to protect their resources and enable their preferred privacy settings.</p>
<p>This specification outlines a simple universal identification mechanism that is distributed, openly extensible, improves privacy, security and control over how each person can identify themselves in order to allow fine grained access control to their information on the Web.

It would have to be served with the mime type <code>application/xhtml+xml</code>.
