I'm +1 for 6.0 and I think this should be made simple in that all 
validation patterns are defined once in the MAP -> VALIDATION object and 
are applied globally.

If you define %foo% and use it in multiple places, I can't see what it 
would mean to validate in one place and not in another.  If people want 
separate validations than they can use separate variables. Maybe if 
someone is getting very tricky and they want it to fail so it defaults 
to a different value based on having multiple defaults that are location 

My take is, rationalize it and make it simple and if we need more in the 
future then add new features in the new framework.
