Hello,

I have the following files I want to export to html:

common.org:
--8<---------------cut here---------------start------------->8---
#+TITLE: Unison Binaries
#+OPTIONS: toc:nil num:nil
#+HTML_HEAD: <link rel="stylesheet" type="text/css" href="style.css" />

* sidebar
  :PROPERTIES:
  :CUSTOM_ID: sidebar
  :HTML_CONTAINER_CLASS: container-sidebar
  :END:

- [[file:index.org::#OSX][Mac OS X]]
--8<---------------cut here---------------end--------------->8---

index.org (extract)
--8<---------------cut here---------------start------------->8---
#+INCLUDE: "common.org"

* body
  :PROPERTIES:
  :CUSTOM_ID: mainbody
  :HTML_CONTAINER_CLASS: container-mainbody
  :END:

** Unison Binaries

*** Mac OS X
    :PROPERTIES:
    :CUSTOM_ID: OSX
    :END:
--8<---------------cut here---------------end--------------->8---

When I try to export index.org to index.html, I get:

Reference "#OSX" in file "index.org" cannot be resolved without
publishing

What does it mean? And why can't the reference be resolved? Should I not
use CUSTOM_ID for relative links?

Thanks,

Alan
