And when it exists in both? Take from a? take from b? take both?
And when there's A for a.example.com in a.db and MX for a.example.com in 
b.db? Does this count as existing or not?
I don't think it's possible. can't you do cat a.db b.db > use_this.db or 
$INCLUDE one of the files in the second?
or maybe ldns-read-zone to canonicalize records and then some awk to filter 
from second zone only records that don't exist in first one.
