How do I define a language ID? | Technology News and Discussion You Care About

I need help to make use of your Keyboard Layout Creator program. It claims that I can do my own Keyboard. Well how can I put a user defined language for my created Keyboard? Let say I have copied the Swedish Standard Keyboard, then I modified that keyboard, give different properties and so on, but it dose not allow me to put any costume Language Name. It is suppose to support languages of the world not countries of the world. I see Non recognised countries but recognised languages like Catalan on the list but I do not see any for Kurdish. Would you please direct me how I can make my created Keyboard available to my users under this language ID?

Thank you ever so much.
