[Bug 1828516] [NEW] avahi-daemon seems unable to advertise _uscan._tcp??

[MarkosJal]

Public bug reported:

I have set up a /etc/avahi/services/scanner.service that looks like this 
                                                                    

<?xml version="1.0" standalone='no'?><!--*-nxml-*-->
<!DOCTYPE service-group SYSTEM "avahi-service.dtd">
<service-group>
<name replace-wildcards="yes">%h <Network_Scanner></name>
<service>
<type>_uscan._tcp</type>
<port>80</port>
</service>
</service-group>

I expected that avahi would then advertise this service (I am shooting
to emulate eSCL, AKA Apple AirScan)

then I run 
avahi-browse -t -r  -a 

there is no service for _uscan._tcp

As I have searched high and low to figure out how to advertise
AppleAirScan/eSCL protocol in avahi and have not found much, perhaps I
am doing something wrong, but seems I should get a mnimaladvertisement
at least.
