Is your feature request related to a problem? Please describe.
Example: if you wanted to have a custom control called "NewsTickerView" with a viewmodel "NewsTickerViewModel". You may want this view to load its own news data so it can be individually unit tested. This view could then be embedded into multiple pages throughout your app without your other viewmodels needing to be coupled to your news ticker.
Describe the solution you'd like
Use the markup extension to register a binding context for controls on a page? How would navigation events get called for these nested controls?
Describe alternatives you've considered
