According to its docstring, `org-publish-resolve-external-link' is used
to resolve the following links:

  [[file.org::*heading][description]]
  [[file.org::#custom-id][description]]
  [[file.org::fuzzy][description]]

It is used by the exporter, and it assumes "file.org" belongs to the
publishing project.

IOW, if you are not writing an export back-end, this is not the right
tool.

I don't know the EPUB exporter. You probably could modify the Org source
itself instead of the output.
