Comment # 5 on bug 1082033 from Dominique Leuenberger

For reference, just some sample services shipped currently:

=============
> cat transmission-client.xml 
<?xml version="1.0" encoding="utf-8"?>
<service>
  <short>Transmission</short>
  <description>Transmission is a lightweight BitTorrent client.</description>
  <port protocol="tcp" port="51413"/>
  <port protocol="udp" port="51413"/>
</service>
=============

As opposed to the one installed by xdm:

<port protocol="tcp" port="6000-6063"/>
<port protocol="udp" port="6000-6063"/>
