    <para>The <emphasis ><property> &quot;label&quot;</property></emphasis > attribute defines text to be represented. If you can use the

    <para>As it was mentioned <link linkend="panelBarItem">above</link>, <property>panelBarItem</property> is used for grouping any
      content inside within one <property>panelBar</property>, thus its customization deals only
      with specification of sizes and styles for rendering.</para>
      <para><property>panelBar</property> could contain any number of child
      <property>panelBarItem</property> components inside, which content is uploaded onto the client
