This feature has only existed since Xerces 2.8. Previous releases do not 
recognize it.

Enabling balance-syntax-trees probably wouldn't help you anyway. It's only 
relevant to large DTDs with element declarations of the form <!ELEMENT 
parent (child1|child2|...|child1999|child2000)>. It's not going to prevent 
a StackOverflowError if your application is walking the DOM recursively 
and happens to overflow the stack in doing so.
