Description

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.
