Hi,
I want to express the following constraint using XML schema :
An unbounded sequence of (A or B) elements which can contain at
most n instances of A.
To illiustrate, I set n = 2. In that case, BABBBBBABBB is valid.
So is AABB . BABABA is not valid because there are more than 2 A
elements in it.
Thanks,
Kenneth
