The less black box testing effort is required in order to verify whether
a specific requirement has been met the better. If you cannot tell the
difference between compliant and non-compliant through black box testing
or if it requires significant effort to do so, such a requirement is
likely out of scope of most W3C Technical Reports (as it isn't useful,
if nothing else). If you restrict yourself to things that are actually
required for interoperability as required in RFC 2119 you are not likely
to run into this problem either.
