Less markup for panel

Created by: Martinomagnifico

Can we get less markup in the panel/accordion? Like the href="#collapseOne" and corresponding id="collapseOne"? When I make an accordion in a group, the a with class accordion-toggle will always target the first next collapse. So not every panel needs an ID in my opinion, or is that against ARIA guidelines or something?

Maybe it can be optional, and if the href/id are not there, the above situation will apply and it will always target the next collapse in the group.
