Yes, there are some exceptions like a business object has many child
graphs/collection with must be validated. In this case, the validation
of the object was done on the WCF service side injecting the object into
a Windows Workflow validation (about 30 steps) with some steps hitting
the DAL for validation with other tables on the ADO.NET EF model.

The object held its error collection messages in the object. The object
was sent back if not valid with error collection messages displayed to
the user.
