Generic property list - default value and required?

Hi!

I'm using the new Generic PropertyList and it works great. However, I have some questions associated with it:

1. How would you set a default value on a property which is defined on the model class? Like when you use SetDefaultValues?
   
   
2. Is the Required-attribute supported for the properties?

Shout if you need a more detailed explanation of what I'm trying to achieve.

Thanks!
