Ok, I'll share my interpretation.

I think it should delete the non-present part (provided they are
optional of course).  What you're doing above would be the result of a
"merge" operation.

This also hold if you have more levels in your config:

<bowler>
  <name>Fred</name>
  <status>married</status>
  <cars>
    <car>
      <id>ABC-123</id>
      <make>volvo</make>
    </car>
  </cars>
</bowler>

+

<bowler operation="replace">
  <name>Fred</name>
  <status>married</status>
  <cars>
    <car>
      <id>DEF-456</id>
      <make>saab</make>
    </car>
  </cars>
</bowler>

=

<bowler operation="replace">
  <name>Fred</name>
  <status>married</status>
  <cars>
    <car>
      <id>DEF-456</id>
      <make>saab</make>
    </car>
  </cars>
</bowler>
