Also, I'd imagine it's a valid use case to want to see some "example data" in the template, when viewed directly, and still set the default to something else.
If that's a requirement, I don't think your proposed syntax will do it, because the webmonkey will see both MISSING *and* John Doe. If that's
That won't be a problem for the web monkey (see below for the reason why) but even if it was the web monkey would then promply do:
<p class="person"> <n:slot name="fullname"> <n:slotdefault style="display:none">MISSING</n:slotdefault> John Doe </n:slot> </p>
which does the trick in Mozilla. Oh well, the web monkey doesn't love IE anyway.. ;-)

It wouldn't be a problem anyway for the web monkey because it is usually a matter of text size, not of actual content: when the page is used as a mockup the actual text is usually some dummy string like "Lorem ipsum dolor sit amet, consectetuer adipiscing elit, sed diam..." while the default text is usually something really short like "-" or "N/A" or "Nothing here sorry".
So even if the mockup text showed "N/ALorem ipsum dolor sit amet, consectetuer adipiscing elit, sed diam..." it would make no difference whatsoever (in most cases).
simpler solution is to do <n:slot name="fullname" allowDefault="true">MISSING</n:slot>. That also has the advantage of not breaking any current code and allowing arbitrary default contents.
+1 for not breaking current code so my preferred solution would be what you suggest but with an added check so that:
if allowDefault="true" *and* there exists a n:slotdefault then take *only* the n:slotdefault content as default value, else if only allowDefault="true" then use the whole contents of the slot as default value, else bail out like it does now.
