    <title>Details of Usage</title>
    <para> The component has the same behavior as standard <emphasis role="bold">
        <property>&lt;h:message&gt;</property>
      </emphasis>component except next two features: <itemizedlist>
        <listitem>It's ajaxRendered. It means that the component is reRendered after Ajax request
          automatically without outputPanel usage</listitem>
        <listitem>The component optionally provides "passed" state which will be shown if no message
          to be displayed</listitem>
        <listitem>Provides possibility to add some marker to message. By default marker element
          isn't shown</listitem>
      </itemizedlist>
    </para>
    <para> Set of facet which can be used for marker defining: <itemizedlist>
        <listitem>passedMarker. This facet is provided to allow set a marker to be displayed if
          there is no message</listitem>
        <listitem>errorMarker. This facet is provided to allow set a marker to be displayed if there
          is a message with a severity class of "ERROR"</listitem>
        <listitem>fatalMarker. This facet is provided to allow set a marker to be displayed if there
          is a message with a severity class of "FATAL"</listitem>
        <listitem>infoMarker. This facet is provided to allow set a marker to be displayed if there
          is a message with a severity class of "INFO"</listitem>
        <listitem>warnMarker. This facet is provided to allow set a marker to be displayed if there
          is an message with a severity class of "WARN"</listitem>
      </itemizedlist>
    </para>

    <para> The following example shows different variants of customization of the component. The
      attribute 'passedLabel' is used for definition the label to be displayed when no message
      appears. But the message component isn't appears before the form submission even with passed
      state defined (on initial rendering).Boolean attribute<emphasis><property> &quot;showSummary&quot; </property></emphasis>defines possibility to
      display summary portion of displayed messages. The facets "errorMarker" and 'passedMarker' set
      corresponding images for markers. </para>

    <para>
      <emphasis role="bold">Example:</emphasis>
    </para>
    <programlisting role="XML"><![CDATA[...
      	<rich:message for="id" passedLabel="No errors' showSummary="true">
      		<f:facet name="errorMarker">
      			<h:graphicImage url="/image/error.gif"/>
      		</f:facet>
			<f:facet name="passedMarker">
      			<h:graphicImage url="/image/passed.gif"/>
      		</f:facet>  	
		</rich:message>

    <title>Look-and-Feel Customization</title>

    <para>For skinnability implementation, the components use a style class redefinition method.
      Default style classes are mapped on skin parameters.</para>

    <para>To redefine appearance of all <emphasis role="bold">
        <property>&lt;rich:message&gt;</property>
      </emphasis> components, you may define the properties of the predefined style classes in the
      common CSS style sheet used on a page (there are no skin parameters and predefined values
      by default to make it compatible with the standard message component). </para>

    <para>To change the style of particular <emphasis role="bold">
