The popularity of the tree-based interface to XML editing is perplexing, given that tree views are quite cumbersome to use for documents with more than a handful of elements at any significant 
level. For "data" documents, the order is usually not so important, so being able to move
branches around is not important; for prose documents, you normally cannot see enough of
the data content to make much use. 

I suspect it is just that Java/VB/C++ have convenient widgets 
for tree-views, so programmers think "oh that is good".  If the desire is to allow some kind
of outlining, but that is to little avail if other word processing features are missing. And, there
is a good proportion of the world which still uses 15" monitors or notebooks: they just cannot spare the screen real estate for any clutter.
