Exposing List Items When Repeated in a Compound Component

I repeat the list of elements in a composite component. I want to show each element of the list so that they can be used in a child component of this composite component to create a template to display all the elements in the list.

Here is my implementation of Composite Component:

customList.xhtml

<ui:component
    xmlns="http://www.w3.org/1999/xhtml"
    xmlns:cc="http://java.sun.com/jsf/composite"
    xmlns:ui="http://java.sun.com/jsf/facelets">    

    <cc:interface>
    </cc:interface>

    <cc:implementation>       
        ...
        ...   
        <ui:repeat value="#{listRetriever.list}" var="item">
            <cc:insertChildren />
        </ui:repeat>

    </cc:implementation>
</ui:component>

Now I want to use #{item}it by defining a child component of a composite component on my page (similar to h:dataTableor ui:repeat).

  <my:customList>
        #{item}                <!--- over here--->
  </my:customList>

<cc:insertChildren> <ui:repeat>, <cc:insertChildren> , . #{item} , <ui:repeat> .

, JSTL <c:forEach> , , <cc:insertChildren>.

xmlns:c="http://java.sun.com/jsp/jstl/core"
...
<c:forEach items="#{listRetriever.list}" var="item">
    <cc:insertChildren />
</c:forEach>

, JSF, . . JSTL JSF2 Facelets... ?.

, , UIData UIRepeat, <ui:decorate>.

customList.xhtml :

<ui:composition

    ... 
    ...  
    <ui:repeat value="#{list}" var="item">
        <ui:insert name="item" />
    </ui:repeat>
    ...
    ...
</ui:composition>

:

<ui:decorate template="customList.xhtml">
    <ui:param name="list" value="#{bean.list}" />
    <ui:define name="item">
