In any case, this seem to be more a linguistic discussion :o)

Who are the others? Amenabar's film? ;o) --> Spanish joke
Seriously, any reference?

Any way, we could name them Host and Subhost if you prefer.

Thus my definition holds

Domain --> example.org

images.example.org, www-inter.example.org and example.co.uk are not included

SubDomain --> example.org

images.example.org and www-inter.example.org are included. Example.co.uk is not

Subdomain --> .org

example.org, images.example.org and www-inter.example.org are included. Example.co.uk is not

Anyway, I'm not trying to do an oficial definition of Domains and Subdomains, I'm just noting that they're usual concepts in web validation and that we should incorporate them to EARL (I want this semantics). We could give these concepts whatever name and definition you want.

No, it just give you the necessary conditions to reproduce it if you need to do so.

Mainly due to different configuration parameters, timeouts, etc.

That obviously get different results too.

The requirement is Web Accessibility
The Test Cases could be WCAG 1.0, WCAG 2.0, Ley Stanca, WCAG 1.0 Level A, Checkpoint 1.1, Checkpoint 3.2...
EARL reports test result of whatever of the previous Test Cases.

If you see a conformance claim as a high level report there is no misuse at all.


Carlos too.
