Can you give some examples they don't cover?

I'm aware of some, for example to mark a list item as deleted you can only 
mark the contents as deleted, not the item itself. But I don't see these 
as major enough changes to require changing the edit markup model.

It looked to me like the use of an attribute in XHTML2 was actually a hack 
to get around limitations of DTDs and of CSS. HTML5's design isn't being 
constrained by either of those so I don't see why edit="" is better.

I actually see inline comments about when things were fixed more often 
than I see "last edited", but that may just be the blogs I frequent.

You can. Wrap those bits you removed in a <del> and wrap the new bits in 
an <ins>.

The information is there with <ins>/<del> as well.


> INS and DEL are IMHO not really appropriate for those kind of edits.

On the contrary, I think they are the kinds of edits most suitable to 
<ins>. It certainly leaves more metadata in the document.

It may be helpful for authors to use these rules:

   ins { text-decoration: none; color: inherit; }
   del { display: block; }
