code: public static void validate(final String xsdFilename, final InputStream in, final ParserOptions options)
          throws Exception
      {
          validate(xsdFilename, new InputSource(in), options);
      }
docs: Wraps the {@link InputStream} into an {@link InputSource} and delegates to
  {@link #validate(String, InputSource, ParserOptions)}.
  <p>
  <b>Note:</b> this method does not set the {@link InputSource#setSystemId(java.lang.String)} property.
  However, it is recommended to use the {@link #validate(String, InputSource, ParserOptions)}  method directly.
  
  @param xsdFilename schema to validate against.
  @param in          document to be validated.
  @param options     to be applied during parsing.
  @throws Exception if an error occurs when parsing the document or schema.
