You mean something like this?:

<summary type="xhtml">
    <w3.xhtml:div>
       This is <b>XHTML</b> content.
    </div>
</summary>

So you're talking about copying the <w3.xhtml:div> element and pasting 
it into a different XHTML file, and finding that the prefix is now 
redundant, right?

But is that really worse than any of these?

In December 2005, The Atom Syndication Format (RFC4287) wrote:

All cases save the last one would work perfectly fine when pasted into 
an XHTML doc using either namespace model, they just become a little 
redundant.  The last one would remain exactly as invalid as it always 
was, unless you define that prefix in your new document.

Am I missing the problem?
