Prompt in Ribbon TextBox/ComboBox (Microsoft Ribbon)

I've been developing a WPF ribbon application using the controls in the System.Windows.Controls.Ribbon namespace. The more I use this, the more I find features missing here and there when compared with other ribbons like the ones from Microsoft Office. One small feature the "prompt" or watermark-type text shown in a ComboBox/Textbox when there is no content (ie. when the Text is blank or when there is no selected item).
Is there any clean way to implement this in the Ribbon controls?

I managed to find a solution. Though it's not an official one from Microsoft, it is remarkably clean and easy to implement. I found this code and used it as a base to make my own attached behaviors for the RibbonComboBox; since RibbonTextBox inherits from the normal TextBox I was able to use the existing behavior (though I did modify it a bit).

In case anyone is interested I attached the code files to this answer. The code not only works for Ribbon controls but for normal TextBoxes and ComboBoxes as well. And is a good solution if you don't want to have to use a separate control or edit the ControlTemplate of an existing one.
