     * @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.
