Now I assume that means that the word "null" translates to the empty string, the empty list, or the empty record depending on the contest. Is it something like a typedef? Where do I learn the definition of the compiler directive "typeNull" ?
I once tried :
set mylist to null
as a way to initialize an empty list and it didn't work. It took an hour or so, including "empty", "nothing", and "nil" to learn that the proper syntax is:
set mylist to {}
which I thought must be something from C rather than "natural English".
Try testing the result of a Choose From List command to see if the return is "null". False is a better choice if you want it to work.
Can you please provide the proper buttons to press in the Script Editor so that I can actually see the definitions in the Type Names suite? Is it a *.h file? As far as I can see the ASLG is absolutely SILENT on the concept.. A search for "null" in AppleScript help, which works only in OS 9.1 for me - OS neXt complains about my internet connection, shows "nothing found".

Applescript syntax is like English spelling:
Roughly, but not thoroughly, thought through.
