Greetings

In reading through the ARIA states and properties spec I am confused
as to whether simulated radiobuttons should use aria-selected or
aria-checked state to indicate currently active o/r checked selected
radiobutton in a radio group.
Both attributes are valid for radiobuttons
The ARIA 1.0 authoring spec recommends using the aria-checked
attribute to check a radiobutton in a set of radiobuttons, does not
mention use of aria-selected.

Is the idea to use aria-selected to indicate the selected radiobutton
and aria-checked as well to indicate its "checked" state?
That does not make sense, because you can only check one radiobutton
in a set of radiobuttons. -- Doing so will uncheck any other option,
so aria-checked is a reliable indicator of the currently selected
option.
So what purpose would aria-selected serve in this context?
Thanks guys
