          public void error(TransformerException e)
                     throws TransformerException

      Receive notification of a recoverable error. The transformer must continue to provide normal parsing events after invoking this method. It should still be possible for the application to process the document through to the end.
      Specified by:
        `error` in interface `ErrorListener`
      Parameters:
        `e` - The warning information encapsulated in a transformer exception.
      Throws:
        `TransformerException` - if the application chooses to discontinue the transformation (always does in our case).
      See Also:
        `TransformerException`

    - #### fatalError

          public void fatalError(TransformerException e)
                          throws TransformerException

      Receive notification of a non-recoverable error. The application must assume that the transformation cannot continue after the Transformer has invoked this method, and should continue (if at all) only to collect addition error messages. In fact, Transformers are free to stop reporting events once this method has been invoked.
      Specified by:
        `fatalError` in interface `ErrorListener`
      Parameters:
        `e` - warning information encapsulated in a transformer exception.
      Throws:
        `TransformerException` - if the application chooses to discontinue the transformation (always does in our case).
      See Also:
        `TransformerException`

    - #### warning

          public void warning(TransformerException e)
                       throws TransformerException

      Receive notification of a warning. Transformers can use this method to report conditions that are not errors or fatal errors. The default behaviour is to take no action. After invoking this method, the Transformer must continue with the transformation. It should still be possible for the application to process the document through to the end.
      Specified by:
        `warning` in interface `ErrorListener`
      Parameters:
        `e` - The warning information encapsulated in a transformer exception.
      Throws:
        `TransformerException` - if the application chooses to discontinue the transformation (never does in our case).
      See Also:
        `TransformerException`

    - #### loadSource

          public InputSource loadSource(java.lang.String href,
                               java.lang.String context,
                               XSLTC xsltc)

      This method implements XSLTC's SourceLoader interface. It is used to glue a TrAX URIResolver to the XSLTC compiler's Input and Import classes.
      Specified by:
        `loadSource` in interface `SourceLoader`
      Parameters:
        `href` - The URI of the document to load
        `context` - The URI of the currently loaded document
        `xsltc` - The compiler that resuests the document
      Returns:
        An InputSource with the loaded document
