I go to the Regions spec:

  http://www.w3.org/TR/2011/WD-css3-regions-20111129/#usecases

and follow the link to:

  http://wiki.csswg.org/spec/css3-regions/regions-use-cases

In that document you find the text I quoted.

Hi Håkon,

I guess I mis-read what you said. The first text you quoted:

is in there. I see that (I had seen that before sending my email).

The second text you quoted:

> >  The following image illustrates the need to be able to insert an
> >  element between two columns.

Is the one I could not find on that page.

I think mistake is that where you wrote:

> > Shouldn't you also have an example, with Steve's pull-quote image,
> > where you say: [...]

the text that follows is your suggestion to introduce Steve's example on that page.

We can add the example, but I would use a different wording. What you propose implies that the requirement for regions and exclusions is to provide a way to position/insert the exclusion between columns. As I was saying in the rest of my answer and other messages, this is not in the scope for these two specifications.

I can add the example and say that it shows an example where an exclusion and a regions are used and note that the positioning in the center of 2 columns would be addressed by other specifications.

Cheers,
Vincent
