The documentation says:

"Warning: This module is considered out-dated and not up to 
Phobos' current standards. It will remain until we have a 
suitable replacement, but be aware that it will not remain long 
term."

My advice is not to use it. I used it a while back, but it slowed 
down my system (why I still don't know), and it is permanently 
soon-to-be deprecated.

If you wanna use D for XML parsing, see if you can find a solid 
3rd party library in D (have a look at Adam's github page: 
https://github.com/adamdruppe/, he has some DOM and HTML stuff up 
there).

There is a new xml module in the review queue, but nobody seems 
to care. I _think_ the reason why nobody really cares is that 
most people in the D community don't like XML.
