IceWM for Guix System

[白い熊＠相撲道]

Hello:

I wanted to set icewm as the WM in my system config - and was surprised 
that it's not in guix. Indeed no historical discussion on the topic 
indicates low interest in this WM in the Guix community. I prefer it to 
XFCE4 though for its simlicity and does most of what I need.

Now, I'd like to add its package definition to my local guix git 
checkout, however my low guix skill doesn't help me currently in 
understanding also the ....-desktop-service-type and everything that's 
needed to be done, and how to then use it in the system configuration.

Can anyone help me - having done that, or similar for another WM that I 
could take inspiration on how this can be achieved?
