For example, the following code define a template called render, and then listbox could use it to render the content of the model (so no ListitemRenderer is required).

<listbox model="${foo}">
<template name="render">
<listcell label="${each.name}"/>
<listcell label="${each.description}"/>
</template>
</listbox>

Notice the use and naming of template depends on the implementation of the component.
