[xep-support] Running header

Hi,
 
In the running header of a page, we want to display the first-starting
article number and the last-ending article number on that page.
Only if the numbers are not the same:
Art.1 - Art. 3
 
If the numbers are the same:
Art.1 (instead of Art.1 - Art. 1)

Any suggestions how we can achieve this? Thanks!

kind regards,

Henk Rutten
