Article update: Creating a compound CCK field

I just updated my article on Creating a Compound CCK Field, to add some information on how to incorporate a node reference field into a compound field (I had a client project that required this, and getting it working was a little tricky). (Yes, I'm still maintaining several Drupal 6 sites for my clients!)

Anyway, I hope someone finds this update helpful! Someone asked me about it in a comment about 6 months ago, but I suppose they either figured it out or gave up long ago...
