		 * Constructor for a new MessageItem.
		 *
		 * @param {string} [sId] ID for the new control, generated automatically if no ID is given
		 * @param {object} [mSettings] Initial settings for the new control
		 *
		 * @class
		 * A wrapper control used to hold different types of system messages.
		 * <h3>Structure</h3>
		 * The message item holds the basic set of properties for a system message:
		 * <ul>
		 * <li> Type, title, subtitle and description </li>
		 * <li> If the description contains markup, the <code>markupDescription</code> needs to be set to true, to ensure it is interpreted correctly. </li>
		 * <li> If the long text description can be specified by a URL by setting, the <code>longtextUrl</code> property. </li>
		 * <li> The message item can have a single {@link sap.m.Link} after the description. It is stored in the <code>link</code> aggregation. </li>
		 * <h3>Usage</h3>
		 * <b>Note:</b> The MessageItem control replaces {@link sap.m.MessagePopoverItem} as a more generic wrapper for messages.
