The spec calls it "the null value" which is included in all domains
(Framework 4.4.2). However, in the same section, it mentions "the data
type of the null value", so apparently each null does have a specific
type.
It seems to me like the spec would have something to say about
ROW(NULL,NULL) versus NULL. Do other systems make a distinction?
