[NTG-context] numbered subitems

[Alan Bowen]

Hi, Aditya—

This works perfectly (after changing the Yen-signs for backslashes).  
It behaves as expected when adapted and will be a great help in  
producing a number of the TOCs that are on my horizon. Many thanks  
for your time and help!

All best, Alan
