[Tagging] Tags for referencing GEOnet Names Server Import

[Saeed Hubaishan سعيد حبيشان]

Hi,

There is a guide in the wiki for importing from GEOnet Names Server 
(GNS) at https://wiki.openstreetmap.org/wiki/GEOnet_Names_Server. And 
this guide (in 2020 version) defines  three tags for importing from GNS 
data:

GNS:id

GNS:dsg_code

GNS:dsg_string (I used GNS:dsg_name instead because it is clearer)

In the talk page 
https://wiki.openstreetmap.org/wiki/Talk:GEOnet_Names_Server there are 
more unnecessary suggested tags  for importing form GNS.

I used these tags in the wiki page for importing from GNS and I describe 
them more in 
https://wiki.openstreetmap.org/wiki/GNS_Import_for_Yemen_and_Others#GNS:id.

There are some protests form users:

and my reply at 
https://lists.openstreetmap.org/pipermail/imports/2021-May/006614.html

I want to share others to return with common view about these tags.
