Accept header recipe in Best Practices

Comment on http://www.w3.org/TR/2006/WD-swbp-vocab-pub-20060314/

The recipe for responding to an accept header only respond to a  
header hich EXACTLY matches
"application/rdf+xml".    However, a client may send (and often will)  
a header with many  comma-separated values, and they may have quality  
parameters (q=0.xx).

This is a serious problem as people are copying the recipe, and  
making we sites which do not work.

If some version of the document could be fixed as soon as possible to  
a recipe that works it would be great.
