Example: Iterate over the children, dependent on a grandchild

In this example, we attempt to retrieve the 'class' of the Llama. A conditional is used against the grandchild node which restricts results to only the Llama. However, the iteration is done over the child, not the grandchild, as indicated by uri="?child" in the action.
