Hi Andrew.  I agree that the XML output should have all the useful
information you find in the normal/interactive output (and then some).
So I added this task to the Nmap TODO:

o We should print host latency (when available) in the XML output, as
  suggested at http://seclists.org/nmap-dev/2009/q4/215.
  docs/nmap.dtd will have to be modified accordingly, and you might
  even consider adding support to docs/nmap.xsl.

But just adding the task won't make it happen!  If someone wants to
step up to the plate and write, test, then send a patch to nmap-dev,
please do so!  This should be a pretty easy one.

Cheers,
Fyodor
