Remarks
Implement IExtensibleObject<T> to enable aggregation of extensions. System.ServiceModel.IContextChannel is an extensible object in Silverlight.
For example, if you are implementing a TreeNode class and want to allow external code to add annotations and methods to some instances of TreeNode, you can have TreeNode implement IExtensibleObject<TreeNode>. This enables code that uses TreeNode to add objects that implement IExtensibleObject<TreeNode> to the Extensions collection.
