The conventions on Windows are all over the place:

All that should be necessary is:

  <summary> Foo </summary>

Adding two attributes and an elements is thus more complicated than 
necessary. This seems pretty unambiguous to me.

If doing so matches the platform conventions, any non-interactive text in 
the <summary> would open the widget.

The author isn't supposed to do this. The whole point of semantic controls 
like this is that the user agent is the one that picks the user interface.

Once we start talking about custom widgets, we're in the space of Web 
components, at which point the author can do whatever the author wants.
