        <para> The <emphasis>
                <property>&quot;value&quot;</property>
            </emphasis> attribute defines the text representation of a group element in the page. </para>
        <para> The <emphasis>
                <property>&quot;icon&quot;</property>
            </emphasis> attribute defines an icon for the component. The <emphasis>
                <property>&quot;iconDisabled&quot;</property>
            </emphasis> attribute defines an icon for when the group is disabled. Also you can use
            the <emphasis>
                <property>&quot;icon&quot;</property>
            </emphasis> and <emphasis>

                <property>&quot;iconDisabled&quot;</property>

                <property>&quot;iconFolderDisabled&quot;</property>
            </emphasis> attributes are defined for using icons as folder icons. The <emphasis>

                <property>&quot;iconFolderDisabled&quot;</property>
