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

I believe David pointed out already that he does not understand this

complicated. The same applies to the evidence property from my side.
