TreeListView with Columns generated and populated by ObservableCollection

Question

Does anyone known (or even has an example) of a WPF based TreeListView that can generate its colums by databinding to the ObservableCollection of its tree items?

For example the databound model is a tree consisting of Employee instances representing the supervisor hierarchy of a company. Each employee addtionally has a ObservableCollection of Responsibility instances (Properties: ResponsibiltyName, ResponsibleSinceDate). Now I want a separate column for each ResponsibiltyName found in any of the databound Employees and the column value should be populated with the ResponsibleSinceDate. If an Employee does not have a certain Responsibilty the column value shall be left blank.

How would one usually approach such a problem in WPF?
