After reading [this question on StackOverflow](https://stackoverflow.com/questions/5913176/in-wpf-why-doesnt-templatebinding-work-where-binding-does) I think it should be noted in the Remarks section what is necessary to get two-way binding to work with a template binding. Right now the Remarks section only tell us that "A TemplateBinding is always a one-way binding..." which suggest that it is not possible to make a two-way binding to a templated parent.
