<p class=MsoNormal><font size=2 color=navy face=Arial><span style='font-size:
10.0pt;font-family:Arial;color:navy'>The reason option (1b) doesn’t make
that much sense is that an XRI is not typically just “resolved to a URL”,
but rather resolved to: a) one or more URIs that correspond to a specified Service
Type identified by a URI or XRI, or b) in a corner case, to one or more URIs
that correspond to the Service Type being null.<o:p></o:p></span></font></p>

<p class=MsoNormal><font size=2 color=navy face=Arial><span style='font-size:
10.0pt;font-family:Arial;color:navy'>In the (a) case, the specified Service
Type would be one of the authentication service types a Relying Party is
seeking, so there would be no need to use the Yadis protocol with the URI. The
(b) case would only be needed if an XRI was used as the value of the
<URI> element inside a service endpoint, which may happen in the future
but I think is a corner case for now.<o:p></o:p></span></font></p>

some changes are not needed and a handbook for implementing in a way that is
open to several schemes.<br>

<p class=MsoNormal><font size=3 face="Times New Roman"><span style='font-size:

Is that different from the following?<br>
