Our use of xri: to define the namespace for XRD and XRDS seems to be  
one of the things that is bothering some of the XRDS-Simple people as  
well as the TAG.

Without giving up on the xri: scheme,  we should consider the wisdom  
of using OASIS  urn:oasis:names:tc:xri:2.0:specs:xrds.xsd or http://docs.oasis-open.org/xri/2.0/specs/xrds.xsd 
    for the namespace going forward.

It isn't that we don't have other ways to declare our XML namespaces.

It will be a pain for something that we consider to be  
inconsequential.  However people seem to fixate on it.

We should develop some strategy about how such a change could be done  
without braking existing implementations in the transition.


We should also have a hard look at Service level refs.

While I was perhaps the biggest advocate if they are going to be a  
barrier to adoption of XRDS we should consider withdrawing them as a  
feature.

Steve and I wrote a whole white paper on there proper use and security  
considerations.   Service level refs are a powerful feature but  
perhaps too powerful at this point.

They could be reintroduced later if there is a demand after XRI is  
more widely adopted.  Saying it pains me greatly!

I think redirects being URI based are mostly an issue of education.   
With XRDS-Simple adding a resolve/resolver-lib  I think they will be  
accepted.

I was thinking that redirects as defined can be to XRI through the use  
of a HXRI.

This has the advantage of also potentially working in a XRDS-Simple  
resolver without XRI resolution abilities.

For Eran's benefit sec 12.3 and 12.5.1 of resolution is worth having a  
look at.

I am looking forward to Eran joining the TC.
