Not "should". As I said, currently, nothing is defined for such checks.
But it should be easy enough to plug in your own checks, no? FWIW, I have the structure in place in my current implementation to add arbitrary keywords which can check whatever you like, but it's an extension out of thin air and non standard (oh, and it's Java).
