My problem is that Odoo localization for my country is out of date. I've read the documentation for creating own localization. 

https://www.odoo.com/documentation/14.0/developer/misc/i18n/localization.html

Even read cybrosis tutorial

The problem is that need additional tax tags that are generated only when the localization is installed. But odoo installs its own localization. I want to know how to create my own localization that I will be installed instead the outdated one?

I've tried inheriting the localisation but it didn't work.

Can someone give me some pointers, how to create a localization that will be installed instead of the odoo-s that is in addons?
