The only issue is that you won't get any error messages if you use 1.1
facilities by mistake, for example maxOccurs on particles in an xs:all group
won't be checked against the 1.0 rules.

I did it this way because some of the new facilities in 1.1 don't involve
new syntax, they involve the removal of restrictions on existing syntax, and
I wanted to make sure that people would get the stricter 1.0 checking by
default, especially as 1.1 is still rather bleeding edge.

If your schema is valid against the 1.0 rules then I don't think there are
any cases where it will behave differently if 1.1 is enabled.
