You're absolutely right! I wrote the code in the e-mail message without 
any testing.

An updated version of that script is attached to this post. The only 
line that has changed is the print() statement.

Good questions... I just use PARTID_UNKNOWN internally for an unknown 
switchback reference. I'll need to clean this up, it's confusing. Don't 
use PARTID_UNKNOWN, I'll remove support for it in the next beta.

Unfortunatelly not. The PDK can't do much about part generation. Also, 
Finale prevents the PDK to make changes to the part name.
