axiom cvc-elt.1.a, only first node validated

Question

I am trying to use Axiom to validate the pom file, but found that except the project can be verified successfully, the rest of the nodes have reported errors

here's my code

  @Test
  public void commonValidate() throws JaxenException, SAXException, FileNotFoundException {
    OMXMLParserWrapper parser = OMXMLBuilderFactory.createOMBuilder(
        new FileInputStream("pom.xml"));
    AXIOMXPath xpath = new AXIOMXPath("//*");
    List<OMElement> elements = xpath.selectNodes(parser.getDocumentElement());
    SchemaFactory schemaFactory = SchemaFactory.newInstance(XMLConstants.W3C_XML_SCHEMA_NS_URI);
    StreamSource schemaSource = new StreamSource(new File("maven-4.0.0.xsd"));
    Schema schema = schemaFactory.newSchema(schemaSource);
    Validator validator = schema.newValidator();
    
    for (OMElement element : elements) {
      try {
        validator.validate(element.getSAXSource(true));
        System.out.printf("Pom element: %s is valid\n", element.getQName());
      } catch (SAXException e) {
        //e.printStackTrace();
        System.out.println("Pom element is not valid: " + e.getMessage());
      } catch (IOException e) {
        e.printStackTrace();
        System.out.println("Error reading pom element: " + e.getMessage());
      }
    }
  }

the xsd file: https://maven.apache.org/xsd/maven-4.0.0.xsd

This is the log printed on the console

Pom element: {http://maven.apache.org/POM/4.0.0}project is valid
Pom element is not valid: cvc-elt.1.a: Cannot find the declaration of element 'modelVersion'.
Pom element is not valid: cvc-elt.1.a: Cannot find the declaration of element 'artifactId'.
Pom element is not valid: cvc-elt.1.a: Cannot find the declaration of element 'build'.
Pom element is not valid: cvc-elt.1.a: Cannot find the declaration of element 'plugins'.
Pom element is not valid: cvc-elt.1.a: Cannot find the declaration of element 'plugin'.
Pom element is not valid: cvc-elt.1.a: Cannot find the declaration of element 'artifactId'.
...

Only the first node is verified, and the rest of the nodes are thrown SAXException.
