Correct, the last two tests may not affect CSS validity (I listed that 
as a separate test) but they may or may not affect the accessibility of 
the served resource. So it really depends on the context of what you are 
testing for. No?

And as to mobileOK, the WARN seems to be a result just like a PASS or 
FAIL not an additional flag as proposed by CarlosI (however, it seems to 
be a kind of PASS too). They also define exactly when the WARN result 
should be issued by using pseudo code for each test. In WCAG we don't 
have a clear definition of when warnings should be issued so this may 
lead to tool developers misusing warning results to satisfy the users 
who don't like to see errors.

That is exactly the problem! ;) ..."nearly-passed" could just as well be 
a fail. For example, "if you just close that one tag your document would 
validate but right now it is invalid" result.

I still don't see a definition for what a warning in the context of EARL 
is. Please propose a definition if you have a suggestion.
