Re: [xri] Minutes:Joint XRI & XDI TC Telecon 10AM PT Thursday 2007-12-20

while i cannot dispute the utility of this proposal, i'd strongly  
urge that the TC work towards a proposal which does not alter schema,  
merely processing rules (as i think that is what i would imagine is  
the challenge for some implementations).  Proposing a lite version  
which breaks compatibility with the present 2.0-cd would be a huge  
mistake.
