You can use the tree views successfully if an event 
on the branch generates the lower branch.  We use this 
for drilling in active data and it works very nicely. 
A static treeview isn't nearly as powerful of course 
and that is an issue when using, for example, 
behaviors in pages.

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.
