But everytime it should be one of: pass, fail, cannotTell, notApplicable or notTested.
As said before, every tool define "warnings" it's own way.

IMO every use case of "warning" is easy to accommodate in one of the EARL validity levels. Then you can use the dc:description within the earl:result to store the warning message itself. After all, are warnings anything else than end-user messages?

Obviously the validity of the test result is a key part of EARL reports, and I don't like the idea of "forcing" tools to understand EARL extensions (validity subclasses) to be EARL-compatible.
