            This method cannot be overridden by derived classes. A
            derived class should override the <span class="nolink">[M:Append(LoggingEvent)]</span> method
            which is called by this method.
            </p><p>
            The implementation of this method is as follows:
            </p><p><ul><li>
            		Checks that the severity of the <span class="parameter">loggingEvent</span>
            		is greater than or equal to the <a href="P_log4net_Appender_AppenderSkeleton_Threshold.htm" target="">Threshold</a> of this
            		appender.</li><li>
            		Checks that the <a href="T_log4net_Filter_IFilter.htm" target="">IFilter</a> chain accepts the 
            		<span class="parameter">loggingEvent</span>.
            		</li><li>
            		Calls <span class="nolink">[M:PreAppendCheck()]</span> and checks that 
            		it returns <span class="code">true</span>.</li></ul></p><p>
            If all of the above steps succeed then the <span class="parameter">loggingEvent</span>
            will be passed to the abstract <span class="nolink">[M:Append(LoggingEvent)]</span> method.
