Xiaoshu, Max, Dan,

I've managed, with your help, to get a somewhat coherent picture of  
what's going on with content negotiation and hash URIs. I've

careful. The approach in the Vocabulary Recipes [1] is correct and  
makes sense.

A long writeup of how I think it all works is at [2]. Comments are
