     * @short A callback for reporting errors.
     *
     * ReportContext receives messages of various severity and type via its
     * functions warning() and error(). In turn, ReportContext create Message instances
     * and submit them to the QAbstractMessageHandler instance returned by messageHandler().
     *
     * The Message attributes are set as follows:
     *
     * - Message::description() - A translated, human-readable description
     * - Message::type() - Message::Error if a static, dynamic or type error was encountered
     * that halted compilation or evaluation, or Message::Warning in case of a warning
     * - Message::identifier() - This is a URI consisting of the error namespace with the
     * error code as fragment. For example, a Message representing a syntax error
     * would return the type "http://www.w3.org/2005/xqt-errors#XPST0003". The convenience
     * function codeFromURI() can be used to extract the error code. The error namespace
     * is typically the namespace for XPath and XQuery errors(as in the previous example), but
     * can also be user defined.
