Response from the Working Group
================================
We do not include any quality checks in our techniques since they are
subjective. “Adequate” is not a testable term. Unfortunately, we do not feel
it is possible to include subjective terms in our testing procedures. We are
clarifying the test procedure to indicate that it should be descriptive.
