      Description

      I have the following schema:

      <?xml version="1.0" encoding="UTF-8"?>
      <xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema">
      <xsd:element name="test" type="Test"/>
      <xsd:simpleType name="Test">
      <xsd:restriction base="xsd:string">
      <xsd:pattern value="[0-9]

      {0,3}([0-9]{3})*"/>
      </xsd:restriction>
      </xsd:simpleType>
      </xsd:schema>

      And this xml file:

      <?xml version="1.0" encoding="windows-1252"?>
      <test>1010000</test>

      I try to validate the file with the following test code:

      DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
      dbf.setNamespaceAware(true);
      DocumentBuilder builder = dbf.newDocumentBuilder();
      Document xsd = builder.parse(Main.class.getResource("/test.xsd").toString());

      SchemaFactory sf = SchemaFactory.newInstance(XMLConstants.W3C_XML_SCHEMA_NS_URI);
      Schema schema = sf.newSchema(new DOMSource(xsd));
      Validator validator = schema.newValidator();

      Document test = builder.parse(Main.class.getResource("/test.xml").toString());
      validator.validate(new DOMSource(test));

      I get an org.xml.sax.SAXParseException: cvc-pattern-valid: Value '1010000' is not facet-valid with respect to pattern '[0-9]{0,3}

      ([0-9]

      {3})*' for type 'Test'.

      In my opinion, the given value should be valid for the given pattern. Even the following code prints "true":

      RegularExpression re = new RegularExpression("[0-9]{0,3}([0-9]{3}

      )*");
      System.out.println(re.matches("1010000"));
