[Caml-list] How to provide additional options for cppo in oasis?

How can an _oasis file pass additional options to cppo?
The documentation of cppo says in its Ocamlbuild section:

 "The following tags are available: cppo_D(X) ≡ '-D X'"

Where are such tags supposed to be?
For extlib I just created a wrapper as a workaround, which calls cppo
with the required options.

The look like ocamlbuild flags that you can pass explicitly in your
_tags file (outside the oasis-controlled zone), or through oasis using
the XOCamlbuildExtraArgs field (you may also need to use
XOCamlbuildPluginTags to enable the cppo plugin):

  http://oasis.forge.ocamlcore.org/MANUAL.html#plugin-ocamlbuild-doc-build

I would expect something like

  XOCamlbuildPluginTags: package(cppo_ocamlbuild)
  XOCamlbuildExtraArgs: -tag 'cppo_D(FOO)'
