I think there is something missing, I will try to articulate it.

* test case
* test scenario
* test suite
* test results

Are all different things. For Example, you might have different 
individual test cases, but in specific cases you will need to associate 
them in a sequence (a test scenario) to demonstrate an implementation 
is working. So the result of the validation is not anymore if each 
individual test went well but more if the sequence went effectively 
with the validation of each test.

So come the notion of conditional testing. If this test XY is positive, 
go to this next test A, if not go to this test B.

I don't think EARL should manage that in the language itself BUT I 
think that EARL should have an architecture that will permit to feed 
the language with parameters. For example a test can be mandatory or 
optional, in this case, EARL should be able to take that into account. 
But it's not necessary something which has to be part of EARL.

We could have a RDF file with all tests indicating if they are 
normative or optional and then EARL would be able to digest it. A kind 
of INPUT API.

In EARL 1.0, the Class Of Products is also very limited. Again it's 
something that could be external, so that it would be dependent on the 
people using it. You will have a file which defines the class of 
products.

For example, in an certification class, you could have different 
evaluation levels
		Web developer
			test 1
			test 2
			test 3
		Webmaster
			test 2
			test 3
		Teacher
			test 1

3 classes of products. But we can't cover all possible cases in EARL, 
then it would be good to give the possibility to declare that outside 
of EARL, saying which format should have these classes of products. :)
