multiple URI elements per Service in XRDs

[Joaquin Miller]

Martin, I was rereading some of the technical messages, to see if we 
missed anything in YADIS 0.9 and i noticed something that might interest you.

>    <Service priority="10">
>      <Type>http://openid.net/signon/1.0</Type>
>      <URI priority="10">https://www.myopenid.com/server</URI>
>      <openid:Delegate>http://keturn.myopenid.com/</openid:Delegate>
>    </Service>
>
>    <Service priority="15">
>      <Type>http://openid.net/signon/1.0</Type>
>      <URI priority="15">http://www.myopenid.com/server</URI>
>      <openid:Delegate>http://keturn.myopenid.com/</openid:Delegate>
>    </Service>

This is just fine.  But notice that the priorities on URI have no 
function.  The only occasion for using priorities on a URI element is 
when there are more than one in a given service element.
