Hello www-qa,

Editing this comment to expand on it a little:

There are several possible classes of extender - implementors, the
original spec writers, writers of another spec that uses the first spec,
users ..... it is perfectly possible to define an extension that does
affect conformance, and indeed this case is discussed elsewhere in the
QA Specification Guidelines document. This case is where the extension
(spec version n+1) removes something that existed in spec version n
(perhaps spec version n had deprecated it already). Thus, content
conforming to spec version n and using deprecated features is no longer
conformant to spec version n+1 and this is expected and encouraged.
