To both make an easy to remember *and* (by Ian's definition) 
unattractive URI, is a challenge ... If one had chosen 
"about:pointless", then no doubt many would have chosen it, in 
order to make a point ... Hence the string should be somewhat 
neutral, so that no one would want to make any points with it ... 
Or, if they were to make a point, then the point would at least 
have a point ...

So, to continue an earlier idea of mine [1], how about

   <!DOCTYPE html SYSTEM "about:dtd-compat">

Such a DTD would be easy to explain - e.g in Wikipedia, which 
allready has an article about DOCTYPES, including the "DTD-less" 
HTML 5 doctype [2]. The new doctype of HTML 5 is one of the most 
striking things about it - many will notice it. And it is easy to 
explain that some old tools expect old doctype syntax, and that, 
for them, the HTML 5 specification has this SYSTEM variant of the 
DOCTYPE, with an about:URI in order to formally fulfill the 
DOCTYPE syntax.
