This is a good point. Requiring optimization of an element node only
makes sense when the use of a feature providing XOP-packaging is
required.

We could indeed imagine a use case where a provider provides two
bindings with XOP support for the same service, and that each of those
bindings have different characteristics and therefore requirements.

One way we could approach this would be to have a xop:optimize element
under binding, which references to the elements to be optimized:

  <binding>
    ...
    <xop:optimize>
      <element ref="id_of_element1_to_be_optimized" hint="required" />
      <element ref="id_of_element2_to_be_optimized" hint="recommended" />
    </xop:optimize>
    ...
  </binding>
