Re: follow-up from EARL project review

[CC'ing ERT WG to share some thoughts and collect input]

Hi DanC,

We haven't actually considered this. Note that not only Assertor is left 
out, but also the Result which is the actual payload of an Assertion in 
EARL. I'm also unsure about the Assertor being uniquely identifiable by 
the context since one of the use cases for EARL is to merge reports from 
different sources. It is therefore important to relate each Assertion to 
an Assertor in an unambiguous way.

Do you see specific advantages in changing the current design of EARL?

Regards,
   Shadi
