        <para>As it was mentioned <link linkend="panelBar">above</link>,
            <property>panelBar</property> is used for grouping any content on the client, thus its
            customization deals only with specification of sizes and styles for rendering.</para>
        <para><emphasis>
                <property>&quot;width&quot;</property>
            </emphasis> and <emphasis>
                <property>&quot;height&quot;</property>
            </emphasis> (both are 100% on default) attributes stand apart.</para>
        <para>Style attributes are described further.</para>
        <para><property>panelBar</property> could contain any number of child
            <property>panelBarItem</property> components inside, which content is uploaded onto the
            client and headers are controls to open the corresponding child element.</para>
        <para>
            The <emphasis>
                <property>&quot;label&quot;</property>
            </emphasis> attribute is a generic attribute.
            The <emphasis>
                <property>&quot;label&quot;</property>
            </emphasis> attribute provides an association between a component, and the message that the component (indirectly) produced.  
            This attribute defines the parameters of localized error and informational messages that
            occur as a result of conversion, validation, or other application actions during the request
            processing lifecycle. With the help of this attribute you can  replace the
            last parameter substitution token shown in the messages. For example, {1} for “DoubleRangeValidator.MAXIMUM”, {2}
            for “ShortConverter.SHORT”.
