I’ve seen a few semi-solutions to this issue but nothing recent and  
coherent.  
What is the best way to use the AR validation system on non-AR objects?  
Seems like this come up enough it should be a HowTo on the Rails site.

Thanks,

-Sam.

Sam,

Why not mixin ActiveRecord::Validations, override #validate, and call  
#valid? when needed?
