Re: [PHP] HTML5 <aside> description

If <aside> is not proper to use for this purpose, what would be?

<sidebar> suggests a particular type of layout.
<section> suggests content.
<nav> is appropriate for some items in a side bar, but not all, and is 
often a child of how <aside> is being used.
<div> give no semantics.

I would like to see a <toc> tag for nav that serves as a table of 
contents of sorts (what I often have at the top of a side bar) but I 
suspect <nav> is considered sufficient.

Maybe <sidebar> would be best, and the reference to column type layout 
can just be understood that isn't necessarily on the side?

Reading up on it, I saw some suggest <figure> for what some of you want 
<aside> used for, but a <figure> is often important content and has its 
own meaning so that's not exactly appropriate.
