Frank Rast commented on XERCESC-1051:
-------------------------------------

Now it does not crash but the performance could be better. Large maxOccurs stil slow down validation. Is there a way to get better performance in this case?

> 200000.
> Assumed cause:
> Stack overfow
> Makeshift resolution:
> Set the repeat count to unbounded(-1), when maxOccurs > 500:
> inline void ContentSpecNode::setMaxOccurs(int max)
> {
>     if(max > 500) 
>         max = -1;
>     fMaxOccurs = max;
> }
