Get StackOverflow when I specify maxOccurs= "25000"

Hi, faced such problem when I specify at an element maxOccurs= "25000", I receive an error with StackOverflow.

But if I specify maxOccurs= "unbounded", validation passes and I get my xml even in 100,000 elements which is marked maxOccurs="unbounded".

Please include a (unit) test to reproduce the problem. Textual explanation and exception is unfortunately not enough to have an idea of what might be happening.

Also: this may well be a limitation of Multi-Schema Validator (component Woodstox uses for validation modes other than DTD), so if there's a test, probably would need to file an issue against that.

Good afternoon. Sorry for taking so long to answer. Sample code with xml and xsd posted here
