Right. The TS parser will assume that a value it finds in an  
assignment which
consists of only uppercase characters is a (TypoScript-) constant.  
Like in
TypoScript 1 you can define constants which can be used everywhere in  
the
TypoScript definitions.

To implement a feature like assigning NULL, TRUE or FALSE, it's  
sufficient
to predefine such a TypoScript constant and set it to the respective  
value.
