Difference between 1.0 and 1.1

[techtonik]

So, if I understand correctly there is no way for consumer to detect which
version - 1.0 or 1.1 is used in HTML delegation case, because delegation
tags are the same, i.e.

<link rel="openid.server" href="http://www.livejournal.com/openid/server.bml
">
<link rel="openid.delegate" href="http://exampleuser.livejournal.com/">
so in my case Drupal consumer decides that either 1.0 or 1.1 version of
specification is used and makes a request to OpenID server with
openid.nsset to either "
http://openid.net/signon/1.1" or "http://openid.net/signon/1.0". But
1.1OpenID server doesn't know anything about
openid.ns, because it was added only in 2.0  Therefore server fails to
authenticate and this should be considered a bug in consumer, which should
not send openid.ns at all. If everything above is right then where is the
logic and what are the reasons for consumer to send openid.ns="
http://openid.net/signon/1.1" at all?

Thank you.
