Andrew Thackrah asks:
>Are version numbers another dimension of variability?

Not in the formal sense. The spec guidelines, currently describing
eight dimensions of variability, apply to one single version. If the
WG keeps enough similarity between versions and specifies backward
compatibility behavior, then a product meeting the later-version
standard MAY be able to deal with the older version by treating it
as another dimension of variability. (That's if the later-version
standard even allows any leeway in backward compatibility.)
