It's both a sensible idea and a silly idea. And it's not new.

It's sensible, in principle, because (assuming it were possible) it would be 
nice to be able to use XSLT to update documents which conform to a W3C 
Working Draft to be documents which conform to a final Recommendation.

Why is it not possible, at least using XSLT 1.0 alone?

XSLT is built on XPath. XPath has no way to access or manipulate the DOCTYPE 
declaration. The DOCTYPE declaration inevitably changes between a Working 
Draft and a full Recommendation. So you can't use XSLT to update all of the 

So, it cannot be done using XSLT alone.
