Aha, ok. This description is not a correct description of the YANG
data tree (in which XPath expressions etc are evaluated). There is
not a single "list node" called "interfaces". Look at an example of
an XML instance document:
<interfaces>
<interface>
<name>eth0</name>
...
</interface>
<interface>
<name>eth1</name>
...
</interface>
</interfaces>
This also reflects the data tree.
