It would be great if you could open an app by voice (“Open Angry Birds”) instead of hunting through 11 screens, or turn on Airplane Mode by voice, or display a certain set of photos.

For other Web technologies, you typically have to create three items: a page to display a document in read mode, a page to display a document in edit mode, and a page to display a view.

Unfortunately XSLT doesn't have any way to ask how a template was invoked, or what the current mode is, so I'll have to do a bit more work to display that information.
