help regarding xsd schema

[santoo]

Hi,

this is my xml fragment

<?xml version="1.0" encoding="ISO-8859-1"?>

<Table xmlns="urn:UMS-application" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance/UMS_APP.xsd">
<Row>
<APP_ID>skumar</APP_ID>
<APP_NAME>1</APP_NAME>
<APP_DESC>Sample test application 2</APP_DESC>
<ACTIVE>true</ACTIVE>
</Row>
<Row>
<APP_ID>10</APP_ID>
<APP_NAME>Test3</APP_NAME>
<APP_DESC>sample test</APP_DESC>
<ACTIVE>true</ACTIVE>
</Row>
<Row>
<APP_ID>11</APP_ID>
<APP_NAME>Test4</APP_NAME>
<ACTIVE>true</ACTIVE>
</Row>
</Table>

this is the xsd schema file for validating the above xml

<?xml version="1.0" encoding="utf-8"?>
<xs:schema id="UMS_APPS"
targetNamespace="urn:UMS-application"
xmlns="urn:UMS-application" elementFormDefault="qualified"
xmlns:xs="http://www.w3.org/2001/XMLSchema">
<xs:element name="Table">
<xs:complexType>
<xs:sequence>
<xs:element minOccurs="0" maxOccurs="unbounded" name="Row">
<xs:complexType>
<xs:sequence>
<xs:element name="APP_ID" type="xs:positiveinteger"/>
<xs:element name="APP_NAME" type="xs:string" />
<xs:element minOccurs="0" name="APP_DESC" type="xs:string" default="" />
<xs:element name="ACTIVE" type="xs:boolean" />
</xs:sequence>
</xs:complexType>
</xs:element>
</xs:sequence>
</xs:complexType>
</xs:element>
</xs:schema>

when I validate the xml using the xsd it is saying validation success.

when I chenge the appid in xml to a string ,or appname to a integer value..still it running with out any errors.wher appid is of type integer and appname is of type string.plzz tell me whether there is any mistake in xsd file.

thanks.
