Saxon

When Saxon DLL is used for validation,

If we are using version 9.4.0.4 (SaxonEE9.4N)

The use of xs:include in the schema throws an exception with the message timeout in Schema compile. This exception is not repeatable if the FeatureKeys.TIMING is set to true. The exception can be reproduced by the code below:

            SchemaValidator schemaValidator = null;
            try
            {
                IList errors = new ArrayList();
                Saxon.Api.Processor proc = new Processor(true);
                //proc.SetProperty(net.sf.saxon.lib.FeatureKeys.VALIDATION_WARNINGS, "true");
                SchemaManager schemaManager = proc.SchemaManager; 

//EXCEPTION

                schemaManager.Compile(new Uri("http://www.example.com/example.xsd"));
                schemaValidator = schemaManager.NewSchemaValidator();

                using (FileStream xmlFs = new FileStream(@"C:\Users\alex.ABC\Desktop\Z\test.xml", FileMode.Open))
                {
                    schemaValidator.SetSource(XmlReader.Create(xmlFs));
                    schemaValidator.ErrorList = errors;
                    schemaValidator.Run();
                }

            }

            catch (net.sf.saxon.type.ValidationException e)
            {
                foreach (StaticError error in schemaValidator.ErrorList)
                {
                    Console.WriteLine(error.ToString());
                }
                Console.ReadKey(true);
                Environment.Exit(0);
            }
            foreach (StaticError error in schemaValidator.ErrorList)
            {
                Console.WriteLine(error.ToString());
            }

After upgrading to SaxonEE9.4.06N the exception (timeout) on second call in Schema compile seems to disappear. However the cause of the problem in earlier releases remains unresolved.
