I working whit Web service in java, axis and Xerces2, this web service get like paremeter an XML, the which use a schema whith restriction, but the validations no work, when i introduce a bad parameter.

Note: The error of validation are write by catalina.out

the xsd and xml was generate whith xmlspy

<?xml version="1.0" encoding="UTF-8"?>
<data xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="1.xsd">
<data1>123</data1>
<data2>1213</data2>
</data>

<?xml version="1.0" encoding="UTF-8"?>

<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" elementFormDefault="qualified">
<xs:element name="data">
  <xs:complexType>
   <xs:sequence>
    <xs:element ref="data1"/>
    <xs:element ref="data2"/>
   </xs:sequence>
  </xs:complexType>
</xs:element>
<xs:element name="data1" type="xs:number"/>
<xs:element name="data2" type="xs:number"/>
</xs:schema>
