Can my WPF Style Setter use a TemplateBinding?

I'm trying to do something like this...

<Style
    x:Key="MyBorderStyle"
    TargetType="Border">
    <Setter
        Property="Padding"
        Value="{TemplateBinding Padding}" />
</Style>

...but I get the error:

'Padding' member is not valid because it does not have a qualifying type name.

How do I provide a "qualifying type name"?

Note: The reason I'm trying to do this, is that I'd like to include the same Border in a series of similar ControlTemplates.

I also tried this:

<Setter
    Property="Padding"
    Value="{TemplateBinding GridViewColumnHeader.Padding}" />

...and it actually compiled, but then when I ran the app, I got a XamlParseException:

Cannot convert the value in attribute 'Value' to object of type ''.

I thought maybe qualifying Padding with GridViewColumnHeader (which is the ControlTemplate I want to use this style with) would work, but no dice.

EDIT:

Well, according to the documentation for TemplateBinding, it says:

Links the value of a property in a control template to be the value of some other exposed property on the templated control.

So it sounds like what I'm trying to do is just plain impossible. I really would like to be able create reusable styles for certain controls in my control templates, but I guess the template bindings cannot be included in these styles.

The {TemplateBinding ...} shortcut is not available in a Setter.

But nobody will stop you using the full verbose version such as:

Value="{Binding RelativeSource={RelativeSource TemplatedParent}, Path=Padding}".
