Validation Errors on Deep Objects

[sophypal]

It would be nice to get validation errors on deeper object models when it's parent is undefined. Right now it ends at the parent model as being required. For example, If I have a foo.bar.baz model and baz is required and the required chain is complete meaning foo and bar are required, having the validation error on baz would be more helpful then having the error on foo because in most cases, the baz is referenced in the view.
