Umdns instead avahi-daemon for announce services

I would like to use standard umdns daemon but it fully ignored .json files in /etc/umdns/ directory. Who knows why?

Below my json file for umdns:

	"adisk_smb": {
		"service": "_smb._tcp",
		"port": 445
	"dev_info": {
		"service": "_device-info._tcp",
		"txt": [ "model=TimeCapsule8,119" ],
		"port": 0
	"timemachine": {
		"service": "_adisk._tcp",
		"txt": [
		"txt": [

At the same time service file for avahi works correctly:

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

P.S. Before experimenting with umdns services I fully disable avahi-daemon, but umdns not announcing any new services after restart. :sob:
