WPF : Define binding's default

Question

In WPF, I would like to be able to template how my bindings are applied by default.

For instance, I want to write :

Text=\"{Binding Path=PedigreeName}\"

Use one of the overloads of DependencyProperty.Register that take a PropertyMetadata. Pass an instance of FrameworkPropertyMetadata and set its properties.

public class Dog {
    public static readonly DependencyProperty PedigreeNameProperty =
        DependencyProperty.Register("PedigreeName", typeof(string), typeof(Dog),
            new FrameworkPropertyMetadata() {
                BindsTwoWayByDefault = true,
                DefaultUpdateSourceTrigger = UpdateSourceTrigger.LostFocus
            }
        );

I don't offhand see a way to set the defaults for NotifyOnValidationError, ValidatesOnDataErrors, or ValidatesOnExceptions, but I haven't used this enough to be sure what to look for; they may be there.
