The horse has bolted for XML 1.0 implementations, so clarifying that
an XML 1.0 implementation should barf when faced with another number
will not cause trouble, I expect.

However, I suggest that for future versions of XML the Core WG adopt
three part version numbers:
with the policy that an XML processor 
  *must* reject a major version number it doesn't know about
  *should* reject a minor number it doesn't know about
  *must not* reject a tweak number if it knows the major and minor

If processors have this policy in place, it would give the WG a richer
vocabulary to work with, and therefore greater flexibility and compatability,
for future versions.

So, to extract the requirement, I think the WG should adopt some numbering
policy for non 1.0 versions of XML which gives them enough flexibility
to maintain and evolve XML with least disruption.
