Does woodstox support substitutionGroup schema element?

[Vincent Vallarine]

I'm using woodstox 4.0.5 to validate xml files against a W3C (.xsd) schema file.  All is good until I use the "substitutionGroup" schema element.


XML Snippet:
...
...
<xs:element name="name" type="xs:string"/>
<xs:element name="navn" substitutionGroup="name"/>
...
...




//my validate routine
public void validate (String xmlInputFile, String xsdSchemaFile) {

                // First, let's parse schema object
                XMLValidationSchemaFactory sf = XMLValidationSchemaFactory
                                .newInstance(XMLValidationSchema.SCHEMA_ID_W3C_SCHEMA);

                File schemaFile = new File(xsdSchemaFile);
                XMLValidationSchema validationSchema = null;

                try {
                        validationSchema = sf.createSchema(schemaFile);
                } catch (XMLStreamException xe) {
                        System.err.println("Failed to process the Schema file ('"
                                        + schemaFile + "'): " + xe);
                        xe.printStackTrace();
                        System.exit(1);
                }

                // And then validate a document:
                File inputFile = new File(xmlInputFile);
                try {
                        XMLInputFactory2 ifact = (XMLInputFactory2) XMLInputFactory
                                        .newInstance();
                        XMLStreamReader2 sr = ifact.createXMLStreamReader(inputFile);

                        try {
                                sr.validateAgainst(validationSchema);
                                /*
                                 * Document validation is done as document is read through (ie.
                                 * it's fully streaming as well as parsing), so just need to
                                 * traverse the contents.
                                 */
                                while (sr.hasNext()) {...
                                        sr.next();
                                }
                        } catch (XMLValidationException vex) {
                                System.err.println("Document '" + inputFile
                                                + "' failed validation: " + vex);
                                System.exit(1);
                        }
                } catch (XMLStreamException xse) {
                        System.err.println("Failed parse the input document ('" + inputFile
                                        + "'): " + xse);
                        System.exit(1);
                }

                System.out.println("Document '" + inputFile
                                + "' succesfully validated.");

}//end validate()

I've validated the file using other parsers so I know the xml is actually valid.


Any ideas?
