JSF components for children

Is there a way to use EL to retrieve a list of children so that I can iterate through it with

<ul>
   <ui:repeat value="#{Magic El expression}" var="children" >
      <li>
      <p> #{children.title} *</p>
      </li>
   </ui:repeat>
</ul>
<div>
 <cc:insertChildren />
</div>

* perhaps #{children.attrs.title} I don't know?

What I'm trying to do here is create a composite component Tab. I know that libraries like primefaces offer tabview etc. But I need to create my own due to the extended functionality of jquery. Plus, I work with a specific template. I need to get the tab title to create a list for tabs. Tabs are components for children, anyway, can I repeat and retrieve their attributes? I mean it looks like this.

If you look at their html markup, they will create an unordered list with the headers of each tabview component for children. How is this implemented?

Composite Component : javax.faces.component.UINamingContainer :

    <c:forEach items="#{cc.children}" varStatus="loop" var="child">
      loop[#{loop.index}]: #{child.getAttributes().get('title')}
    </c:forEach>

, - JSF, , #{cc} #{component}
