Yesterday while looking for a totally unrelated topic I came across the "PropertyPath XAML Syntax" MSDN page (http://msdn.microsoft.com/en-us/library/ms742451.aspx) and saw the "Single Property, out of XAML Loading Namescope, Run-Time Reflection" header (near to the middle of the page). Even though I have been programming WPF for years now, I've never saw this type of use of the Binding class. I am just curious where and exactly in which syntax (how do you declare the qualified type name in markup extension??) this binding type is used? Any feedback is greatly appreciated.
