[reSIProcate] Privacy header parsing

[Byron Campen]

	I have looked at this a little closer, and it looks like the spec  
isn't saying what you think it is. To wit, this:

Privacy: user;session;critical

is not equivalent (conceptually or otherwise) to this:

Privacy: user
Privacy: session
Privacy: critical

"user;session;critical" is a single header-field-value in this case,  
and cannot be separated. Now this begs the question, is Privacy a  
multi-valued header or not? Can you have something like the following?

Privacy: user;critical
Privacy: header;session

(This could convey that user anonymization is critical, whereas  
header and session anonymization would be nice to have)

	I can find nothing in 3323 stating whether or not Privacy is single- 
valued. Has this been clarified somewhere?

Best regards,
Byron Campen
