Few other minor points.
1) You write in your XSD as following,
<xsd:sequence maxOccurs="unbounded">
<xsd:element name="A">
...
I'd suggest following (I believe, this is more commonly followed),
<xsd:sequence>
<xsd:element name="A" maxOccurs="unbounded">
...
2) In your file, NEW_PROBLEM.xml you write
<root xmlns="NAMESPACE"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
xsi:schemaLocation="NAMESPACE PROBLEM.xsd">
...
I guess, it should be
<root xmlns="NAMESPACE"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
xsi:schemaLocation="NAMESPACE NEW_PROBLEM.xsd">
....
(NEW_PROBLEM.xsd instead of PROBLEM.xsd)
Looks like this is a typo within your file.

> Issue Type: Bug
> Components: XML Schema 1.1 Structures
> Affects Versions: 2.12.0
> Reporter: Gerben Abbink
> Priority: Major
> Attachments: Java Heap Dump.png, NEW_PROBLEM.xml, NEW_PROBLEM.xsd,

> The validation of xml against asserts in XMLSchema 1.1 is slow and takes up a
> lot of memory for larger xml files. I have created a simple test xml file
> with lots of repetition and a corresponding xml schema to show the problem.
> It takes 20 sec. to validate the xml against the xml schema. When i remove
> the asserts in the xml schema it takes just 1 second to validate. Testing was
> done from the command prompt on a modern Windows machine with 8GByte memory.
> To compare, i have also validated the xml file against the xml schema in
> XMLSpy. With asserts it takes 2 sec., without the asserts 1 sec. (XMLSpy does
> not uses Xerces.)
