decoupling from HTML

Tue Jun 28 11:20:33 PDT 2005

To help maybe answer my own question is there any reason why, if the link 
tag is not found as previously defined to then check the same directory 
specified for an openid.xml file which would be a minimal atom feed such as:

<?xml version="1.0" encoding="utf-8"?>
<feed version="0.3" xmlns="http://purl.org/atom/ns#" xmlns:dc="
http://purl.org/dc/elements/1.1/"
xml:lang="en">
<title><![CDATA[<XSLT:Blog />]]></title>
<link rel="openid.server" href="http://xsltblog.com/openid-server.app"/>

</feed>

This would allow for the existing spec to work as is with the added 
insurance policy to allow a request for a specific atom xml file to override 
any potential web server issues that serve up other page formats based on 
the client.

This would also add bits of other information pertaining who the user is, 
etc... possibly for a richer user experience but thats obviously beyond the 
scope of OpenID but within the scope of standards compliance which will 
allow for such information to be more easily consumed at the visiting site.

Thoughts?
