Composite type evaluates to Null if any element is null

I have just re-read chapter 8.15 of the 8.3 manual and I am
understanding why a composite type would evaluate to NUll if any of it
elements are null.

Can anyone explain this behavior?  To me if I have a composite type
column and there are some values in it, its incomplete, yes, but not
null.

Thanks for the feedback.
