tho' there are degrees of "work". A fast but inaccurate answer may be better than a "perfectly correct" answer. Sometimes "in good time" is an essential part of the requirement. Your car's anti-lock brakes can't spend hours or minutes deciding the best time to put the brakes on (or take them off).

"don't prematurely optimise" is not an excuse to "prematurely pessimize". Besides if it's been properly designed (see Rule 2) the XML blob will be hidden behind an abstraction and a real database be shoved in with little trouble (I'm aware swopping databases isn't quite as easy as this- but it should be!).

there other things can't be added on afterwards eg. security
