I found it from googling around, but there is an sample, the avahi-service.dtd should describe it - in example below the Xserve is of course just for giggles;)

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE service-group SYSTEM "avahi-service.dtd">
<service-group>
    <name replace-wildcards="yes">%h</name>
    <service>
        <type>_smb._tcp</type>
        <port>445</port>
    </service>
    <service>
        <type>_device-info._tcp</type>
        <port>0</port>
        <txt-record>model=Xserve</txt-record>
    </service>
</service-group>
