I don't really see the advantage above using ordinary lists or form controls
and css pseudoclasses like :target ,:focus and :active

>     I'm proposing a new element named <sl>. This element is a list where

> | <sl>
> |   <li><a href="#s1">Section 1</a></li>
> |   <li><a href="#s2">Section 2</a></li>
> |   <li><a href="#s3">Section 3</a></li>
> | </sl>

>
> | li:selected { /* Your style here. */ }

>     By default, the selection would be mutually exclusive. In other
> words, the default for clicking on a list item is that it would become
> the ONLY selected item, similar to <select>. Also similar to the
> <select> element, you could specify a |multiple| attribute to select

>
> | <sl multiple="multiple">
> |   <li>Name 1</li>
> |   <li>Name 2</li>
> |   <li>Name 3</li>
> | </sl>
>
>     If multiple items are selected, and the user performs a drag
> operation on a list item, the drag would automatically be performed on
> all list items selected rather than just the list item being dragged.

> | <sl>
> |   <li selected="selected"><a href="#s1">Section 1</a></li>
> |   <li><a href="#s2">Section 2</a></li>
> |   <li><a href="#s3">Section 3</a></li>
> | </sl>

> | <switch>
> |   <section active="active" id="s1">[...]</section>
> |   <section id="s2">[...]</section>
> |   <section id="s3">[...]</section>
> | </switch>

> CSS:
> | sl > li { appearance: tab; display: tab }
> | sl > li:selected { display: front-tab }
