Adding strings to meta data

I have noticed that mods that use meta data to run it (war3map.w3a etc) do not reference any strings from war3map.wts. An example of such a mod is TTOR. So i was wondering if there was any secret easy way of getting the strings into those files, or if its just pure copying each string reference with its actual text.

EDIT - I just realised i posted this in the wrong place. DArn it!!!!
