If nothing else, when a derivative is not required, only specifying 
schema items once (presumably in Schema.pm) certainly makes updating the 
schema and interactions easier. :)  I suggest we work toward removing 
duplicate definitions like the example I gave originally for code 
maintainability purposes. :)  If nothing else, it seems that we ought to 
at least ask Schema.pm for the type definition as opposed to re-coding 
it again in another area - again for maintainability reasons.

I also wonder if moving the database upgrade section of checksetup.pl 
into Schema.pm also makes sense so it's all in one place, possibly to 
Schema::check_and_upgrade_db().  Again, I say this because I'm thinking 
about maintainability - if all the core Schema changes are limited to 
Schema.pm, I believe that it should make it easier for maintainers to 
keep the number of files they touch down when making changes to the 
schema itself.

Back to my version per component work... :)
