This doesn't seem very useful at the moment, but it will make
sense once we introduce another HPT-related setting.
The output XML is decoupled from the input XML in preparation
of future changes as well; while doing so, we can shave a few
lines off the latter.
This commit is best viewed with 'git show -w'.
