Worth noting that some of these processors have since changed the way that
they check maxOccurs. For instance Xerces-J used to always build up a state
machine proportional to the size of maxOccurs. Now it represents these with
a single state for simple cases (e.g. maxOccurs > 1 on
xs:element/xs:wildcard) which loops with a counter to track how many
instances there are.
