Re: Changing semantics via ARIA Role

The short answer:
If you make it look like a duck, it also has to quack like a duck,
feel like a duck and taste like a duck.
If you start with an anchor tag and slap role="button" on it, make
sure it looks like a button and can be activated with enter or space
bar (because that is how the button element works).
If you start with a div, you have to make it focusable, assign the
button role, assign an accessible name, make it look like a button,
make sure its click event is fired when user presses spacebar or
enter key etc.

If you do all of those things, you can use ARIA to create widgets.
If you tell the user you have a button, the user should never be able
to find out (without inspecting your code) that, in fact, it isn't.
