Hi Tim,

English isn't my first language, but doesn't 'error' indicate that  
someone basically knew how to do something and erred (not always the  
case with the problems we encounter)? Maybe 'flaw' is the more  
accurate term? 'Failure instance' sounds pretty stilted and may easily  
get mixed up with (WCAG) Failures.

Mhm..(scratching head)...mhm.

Quoting "Boland Jr, Frederick E." <frederick.boland@nist.gov>:

> According to some references I recently accessed, criticality
