Silverlight 4 Bind selected items' (more than one) properties to a textbox

I have an editor where the user selects a photo from a listbox in SL4, and edits the values like title, description, tags in a panel next to the list. The textboxes have Binding is XAML to the listbox's SelectedItem's appropriate properties, and it works nice. However, I want to be able to select multiple photos at the same time, and say, set tags of each. I don't know the exact name of the problem but I tried to explain, it is a very basic functionally in any software, select multiple items and edit a property, and it will be edited for all of them. If the properties are different, the textbox would display (multiple values) and if I don't touch the field, nothing happens to those fields. Is this possible in XAML? I'm pretty sure up until SL version 4 is released, Microsoft guys would have thought a clever solution to this multiple-selection problem. If yes, how (please, XAML and Binding based declarative as possible or everything easily gets messed up). If there is no starightforward way, what is the cleanest/best practice of doing this?

You can use ListBox.SelectedItems to enumerate and change the property of each item in the selected list. The ListBox should have SelectionMode as Multiple.

Its not a proper way to bind multiple items properties to a textbox, as we don't know what to show when these items have different values, & its better to have ListBox, and all its properties binding to a collection and its properties
