Hi,
 
I want to reference a headline inside another headline, and showing the section number when exporting to html.
 
So suppose I have an org file:
 
* headline A
* headline B references <<headline A>>
 
When export to html, I want to see the following:
 
1 headline A
2 headline B references 1
 
How do I do that?
 
Thanks,
Ning
