I finally had a chance to pull out my copy of E1.11-2008. In section 8.5.1 it says:
"Once a controller is configured for a particular application, all NULL START Code packets should have the same number of slots."
Now, that's a "should", not a "shall", so variable length NSC packets don't strictly violate the standard. Still, it's a *very* bad practice.
