The "0" isn't specifying the element of the <peer> section to modify;
it's specifying the child-element of <peers> to alter.

The XML tree looks roughly like this:
<ntp-client>
  <peers config:type="list">
    <peer>
      <address>xxxx</address>
      .....

So, the path would be ntp-client,peers,peer,address -- _but_, the
"config:type=list" changes that.  Since it's a list, just specifying the
name of the element that you want to modify is ambiguous (even if
there's only one element with that name).  

So, in the case where there's an element in the path with
config:type="list", you need to specify the index of its child that you
want to modify, instead of the name of the child.  That's what the "0"
is doing.
