The system_msg block is reserved for displaying messages to the user regarding the current state of the application or the results from an operation. They are completely optional.

The HTML for a message is generated for you when you use the <mtapp:statusmsg> template tag. The style of the message (success vs error) is set using the class argument on the tag, and the message itself is defined by the contents of the tag. For example:

<mt:setvarblock name="system_msg">
    <mt:if name="saved_deleted">
        <mtapp:statusmsg
            id="saved_deleted"
            class="success">The selected events were deleted.
        </mtapp:statusmsg>
    </mt:if>
</mt:setvarblock>

To change the style of a message use one of the following classes:
