I prefer that we keep this as an issue.  Although I
understand your reasons for not wanting empty values, there
may be good reason for attributes whose values are a set of 0 or
more values. 


The issue is that you would like to represent the NULL Set by
a set having a special member which cannot coexist with other members.
This solution may add more complexity than we are removing.
