What the trigger was:
Tibor2 asked me in the comments of my user file post 
"MiG-29A (full-fidelity), Fictitious Swiss Air Force Skin (DCS 2.9.20+)" 
-- see https://www.digitalcombatsimulator.com/en/files/3346981/ -- 
whether I could "... do the same for Czech and Slovak livery ... ".

Well, the trick is simple:
Just adapt the "description.lua" file to the required format
of the skin description file for the full-fidelity (FF) MiG-29A model.

This FF format consist in different 'key names' for the assignment
of the texture files (*.dds) compared to the Flaming-Cliffs (FC) format.

Now, luckily the format of the texture files for the FF model 
is almost the same as for the FC model. And so we can use most
texture files from the FC MiG-29A also for the FF Mig-29A.
We just have to assign the same textures do different 'key names'
in the respective "description.lua" file for the FF skin.

E.g. instead of writing the below line in the FC "description.lua" file
for a MiG-29A FC skin
	{"mig29_tex1", 0, "mig-29_tex01", false};

we now have to write the below line in the FF "description.lua" file
for a MiG-29A FF skin
	{"mig29a_ext01", 0, "mig-29_tex01", false};

See, only the first parameter (key name in parentheses) is different
but the texture file name "mig-29_tex01" is the same. And the same
applies to all the other key names for an FF "description.lua" file.

In order to get acquainted with the new key names it is propably best
to analyse an existing FF skin description file.

One important thing is the Livery subfolder name which is needed
to hold the new MiG-29A (FF) skins which is
  "MiG-29-Fulcrum"
  
So, to do:
1.  Create a subfolder "MiG-29-Fulcrum" within your 
    "<DCS.version>\Saved Games\Livery" folder.
2.  Copy any MiG-29A FC skin into the "MiG-29-Fulcrum"
    e.g. if you have that FC skin installed:
         copy the complete skin folder "CzechAF - #5918" 
         (which contains the respective description and texture files) 
         from the FC "\Saved Games\Liveries\Mig-29A" folder
         to the FF "\Saved Games\Liveries\Mig-29-Fulcrum" folder.
3.  Modify the (FC) "description.lua" file contained in the FF folder
    in order to adapt to the FF "description.lua" file format.
4.  Also copy a 'nose and fin' texture file from an existing FF skin
    into your new FF folder because this texture format is very different
    compared to the FC variant.
    I took the "mig29a_ext09_gdr.dds" texture from the game installation folder
      \DCS World\CoreMods\aircraft\MiG-29-Fulcrum\Liveries\MiG-29-Fulcrum\GDR
5.  Take note that the board number key names in an FF skin description
    are different compared to an FC skin description.
    For an example refer e.g. to my FF SAF MiG-29A skin description.
