I'd like to use aspects, but I'm developing for v4.3 where you AFAIK  
can't use AOP.

You're right that "required" is actually a field property and that  
validation is a different aspect. Thanks for the clarification.

However, chaining validators with OR and AND would be great as  
combining validators would be a powerful tool that allows one to keep  
the validators simple. Don't get me wrong, I don't want to put all the  
logic in the comment-block, but right now I can't access the  
DisjunctionValidator because everything is concatenated with AND.
