How to use list?

Hi,
I have a question about lists:

My schema:  testList.xsd
----------------------------
<?xml version="1.0" encoding="UTF-8"?>
<xsd:schema xmlns:xsd="http://www.w3.org/2000/10/XMLSchema"
elementFormDefault="qualified">
 <xsd:simpleType name="IntegerListType">
  <xsd:list itemType="xsd:positiveInteger"/>
 </xsd:simpleType>
 <xsd:element name="IntList" type="IntegerListType"/>
</xsd:schema>




My xml file: XML SPY V3.5B3 does NOT validate
-------------------
<?xml version="1.0" encoding="UTF-8"?>
<IntList xmlns:xsi="http://www.w3.org/2000/10/XMLSchema-instance"
xsi:noNamespaceSchemaLocation="C:\ArcIMS\AXL\testList.xsd">5 5</IntList>

XML Spy says:
Invalid value for datatype positiveInteger in element 'Text'


My xml file: This one validates fine (only one in the list)
------------------------------------------------------
<?xml version="1.0" encoding="UTF-8"?>
<IntList xmlns:xsi="http://www.w3.org/2000/10/XMLSchema-instance"
xsi:noNamespaceSchemaLocation="C:\ArcIMS\AXL\testList.xsd">5</IntList>



Is it a problem with my xsd or XML Spy?
