well, there are better reasons... such as that it means more disk IO, is 
slower due to run-time XML processing, is more fragile since it can be 
changed post-compile which is when programmatic manipulation of the UI is 
cemented, etc....

and why does this matter? you don't hand-edit it, though i have done just so 
on several occassions. it's like saying that the code MOC outputs is ugly. 
yeah, so?

the DTD is largely irrelevant and XMLGUI is completely not suited for this 
sort of thing (it's very good at something rather different).

Qt Designer as a tool is _very_ useful, and has several important positive 
side effects. please use it whenever and wherever possible for complex (e.g. 
more than a 2 or 3 widgets) dialogs and sets of widgets.
