I think Jim is right that we need to be able to identify tests, and  
provide at least basic descriptions of them.

We also need to describe how a set of tests relates to a different set of  
tests in terms of the fact that two different tests or sets might imply  
something about the result of a third test. This is not about testing  
process, but about the equivalence between results - for example passing  
Hera's test for text alternatives on images implies that you will pass  
Chris' test that there is an alt attribute for each img element.

I think both of these can be done by virtue of the fact that EARL is RDF,  
using the basic framework stuff it gives us (RDF Vocabulary Definitions,  
OWL, etc) rather than having to define anything in EARL itself. This  
strikes me as a good thing...



(Lots of context below)
