Backported fix for XERCESJ-773: build a representation of large minOccurs/maxOccurs in constant time and memory (which uses a counter during validation) for element and wildcard particles when each model group particle in the content model:

* has minOccurs/maxOccurs == 1; or
* contains only one element/wildcard particle with minOccurs/maxOccurs == 1
