[Semi-OT] Sdlang Initiative

[singingbush]

It's worth pointing out that SDL (as in Simple Declarative 
Language) isn't being actively developed anymore. I reached out 
to Daniel Leuck about it a few years ago as there were a few 
things I'd wanted to see in an updated spec. There was some 
discussion about an updated specification for SDL but in the end 
it was decided that development would focus a family of languages 
under the name of Ki. One of which, [Ki Data 
(KD)](https://github.com/kixi-io/Ki.Docs/wiki/Ki-Data-(KD)), is 
essentially the newer replacement for SDL. As shown in the linked 
documentation, a `*.kd` file is similar to `*.sdl` but there is 
far more documentation about the newer standard.
