Note that the anser to this depends on the outcomne of Y04. Andy has
strong objections to Y04-02, and proposed Y04-04 instead.
Assuming Y04-02, and assuming /foo has the value 20 and the oper rpc's
result has foo = 10, the accessible tree would look like this:
<root>
+-- oper
| +-- foo = 10
+-- foo = 20
(If we instead move back to Y04-04, the accessible tree would be:
<root>
+-- oper
+-- foo = 10
)
