DOMSource and StreamSource both provides setSystemId API for setting base ID for file reference. When using StreamSource as InputSource for Transformer, the base ID get resolved

FileOutputStream fos = new FileOutputStream("dom.out");
        InputStream xmlStream = new FileInputStream("SystemIdImpIncl.xml");
        TransformerFactory factory = TransformerFactory.newInstance();
        Source xslSource = new StreamSource(new InputStreamReader(new FileInputStream("/test/SystemIdImpIncl.xsl")));
        xslSource.setSystemId("file:///test");
        
        Source xmlSource = new StreamSource(xmlStream);
        factory.newTemplates(xslSource).newTransformer().
                transform(xmlSource, new StreamResult(fos));

DOMSource doesn't work for this case, the file wasn't correctly parsed and it doesn't throw any error.
       FileOutputStream fos = new FileOutputStream("dom.out");
        InputStream xmlStream = new FileInputStream("SystemIdImpIncl.xml");
        TransformerFactory factory = TransformerFactory.newInstance();
        DocumentBuilder docBuilder = DocumentBuilderFactory.newInstance().newDocumentBuilder();
        Node xslNode = docBuilder.parse(new InputSource("file:///test/SystemIdImpIncl.xsl"));
        Source xslSource = new DOMSource(xslNode);
        xslSource.setSystemId("file:///test");
        
        Source xmlSource = new StreamSource(xmlStream);
        factory.newTemplates(xslSource).newTransformer().
                transform(xmlSource, new StreamResult(fos));
