The distinction between editable and not editable in Nvu is based on
attributes, themselves triggering CSS styles. Basically, that's all about
the -moz-user-select property...

It's not even valid HTML because I'm adding new attributes to HTML content.
On the plus side:

   (a) MSIE did that long ago

   (b) I have always had the feeling the did the-right-thing, and I remember
       telling Tantek about it in the train when we left the Cleveland CSS WG

   (b) it's stylesheet-agnostic. I do believe this is behavioral and not
       **at all** presentational. Saying an element is or is not editable is
       presentational. Saying an element is repeatable is not, IMHO.

That's a neat idea, but, again, I think the path opened by MSIE **SEVEN**
years ago was a good one. And because I think (a) this is not presentational
but behavioral (b) this is not only for HTML, I believe we should have an
xml:editable attribute.

If this happens to be impossible for almost religious reasons, then I
_could_ live with such a solution but it would be quite bad design, IMHO.

I don't understand this at all.

Restricting content insertion on block/inline status is more important.

You also miss a way to say an element is

   1. resizable
   2. movable
   3. foldable
