They are optional *if* the server does not do any content negotiation, 
otherwise HTTP in RDF shall be used. Shouldn't it?

I think this has nothing to do with EARL. Tests must have a timestamp. 
Whatever happens afterwards it is beyond the scope of EARL. The Web is 
intended to change ...

I believe David pointed out already that he does not understand this 
methodology purpose, neither do I. We are making EARL unnecessarily 
complicated. The same applies to the evidence property from my side.
