Hi Willy,
There are places in your schema where you set maxOccurs to very large
numbers:
<xsd:element name="container_info" type="container_infoType" minOccurs
="0" maxOccurs="9999"/>
<xsd:element name="item_detail" type="item_detailType" maxOccurs="9999"/>
<xsd:element ref="shipping_marks" minOccurs="0" maxOccurs="999"/>
<xsd:element ref="goods_desc" minOccurs="0" maxOccurs="999"/>
Do you really mean that? Wouldn't maxOccurs="unbounded" be a better choice
in this case?
I have to admit that, in one way, this is a limitation of Xerces-J. Your
element "container_info" is expanded to 9999 optional elements
(min=0/max=1), which causes the stack problem when we recursively traverse
these elements.
We can design certain algorithm to solve this problem, but it would greatly
complicate the program, hence affect the performance. And we don't see
enough demand for it yet.
