Checking the rules for values set and tested

Suppose we have these two decision tables.

The first table determines a person's category based on age

The second table uses that category to determine something else.

Do you see some potential problems with these tables?

The validation engine will observe that:

Attribute category is set to 'unborn' by a rule but the value is never tested by any other rule
Attribute category is set to 'adolescent' by a rule but the value is never tested by any other rule
Attribute category is tested for ='teen' but no value in this range is ever set by a rule

There are other problems too with these rules:

if age in months in[12..13) then result not specified 
if age in months >17 then result not specified
