During yesterday's teleconference, the following text was proposed:
"URI comparison SHOULD be done character-for-character"
Your proposed text looks very similar, but takes a different angle, and 
actually I prefer yours :)
Is the WG ok to resolve 502 with this text instead of the originally 
proposed one?

Also note that the Rep header is just there to provide locally a 
representation, it is not required that this representation will be used, 
so if the match is character-for-character and URI are similar, but 
written differently, it is not a big issue if an implementation fail to 
associate them.
