Subj:   Re: Nulls in a composite Primary Key deployed as a Primary Index
From:   Paul Johnson

On the few occasions that I have used a 'special value' to populate a column it has been set to the biggest negative number that will fit in the column, on the grounds that this is very unlikely to ever happen in the real world. However, I can't imagine using either nulls or a 'special value' in a composite primary index.
