Solution

Template:

<ui:composition>  
       <ui:insert name="wa_content"></ui:insert>
</ui:composition>

xhtml page (with another include):

<ui:composition template="template_name">

        <ui:define name="wa_content" >
              <ui:define name="buttonsPanelBody" >
                        <ui:include src="other_xhtml_page_name.xhtml" />
              </ui:define>
        </ui:define>
</ui:composition>

other_xhtml_page_name.xhtml

<ui:composition>
