>    Affects Versions: 2.5.0
>         Environment: Operating System: Linux
> Platform: PC

>
> When validating an instance of an XML order against its schema, the process took
>  5 minutes 7 seconds and required an increased maximum heap size to run to
> completion.
> The problem was traced to a maxOccurs value of 9999 on an element (the
> OrderLine). Changing this to unbounded reduced the time taked to 1.16 seconds
> and required no increase in the default heap size.
