There are at least four examples in the spec that show <div> and <article> 
or <section> used together.

I'm happy to add more, if you have any specific requests.

If you have any concrete examples I could include, I'd be happy to do so. 
I'm probably not the best person to be writing such examples, though.

Rather than reworking examples, let's just add more. :-)

Any time frame is fine; I'll add them whenever they are available.

The code above seems fine, though I probably wouldn't bother with the 
<div> (either using a <p> or nothing at all, depending on what else is 
there). You could also use an <iframe> instead of the <img> in the 
"detail" div, so that you don't need JS. And of course there's a bunch of 
missing alt="" attributes that are required in HTML5 (and 4).

It maybe could have a section, but I'd have to see the rest of the page to 
say for sure. Doesn't seem necessary though.

I would probably remove the <div> altogether.

Unless it could be removed without significantly changing the meaning of 
the page (which seems unlikely here), I would say no.

It doesn't seem like a navigation menu to me.

Neither makes sense without the other, so I'd be skeptical of that line of 
reasoning.

Document, app, it doesn't matter. There's a spectrum, and few things these 
days are at either end of the line. Is the HTML5 spec itself a document or 
an app? (It has plenty of scripting.) It doesn't matter.

Sure, it's basically the same thing. In fact I suggested above that this 
might be the way to do it. :-)

I'd say that is poor UI, but apart from that it's neither here not there.

It doesn't.

If you printed the page, would you say they were in different sections?

Indeed.

The header guideline is a reasonable one, though it should be noted that 
just because you _could_ put a header at the top of each section doesn't 
mean you necessarily _should_ or that you would want to.
