Can I get RangeAttribute functionality in my own code?

Question

A bunch of cool attributes were introduced in .NET 3.5 SP1 to help with property validation. They are in the System.ComponentModel.DataAnnotations namespace and can be used like this:

public class Person
{
  [Range(0, 120)]
  public int Age { get; set; }
}

Technologies like Dynamic Data, MVC, and Silverlight automatically use the attributes to enforce validation.

However, the code above still allows the following to run without throwing an exception:

Employee emp = new Employee();
emp.Age = -23;

What I want to know is can I harness these attributes in my own application (which is not Dyn Data, MVC, or Silverlight)? I had hoped that the code above would throw a validation error when the invalid value was assigned to the Age property. Or do I need to continue using the traditional validation inside the property setter like this:

private int _age;
public int Age
{
  get { return _age; }
  set
  {
    if (value < 0 || value > 120)
    {
      throw new ArgumentOutOfRangeException();
    }

    _age = value;
  }
}

Maybe there is another approach that is a best practice?
