I think it might be useful to have a leading-model property that allowed 
you to change how line-height works. But it might also be more complicated 
than it’s worth. In my experience, sticking with a single leading model is 
the only way to reasonably lay out lines. The boundaries between leading 
models almost never give you the results you want.

There are a few different ways to deal with leading. I’m assuming you’re 
looking for one of these:

1. line-height sets the baseline-to-baseline distance 
  (font-size of 16px and line-height of 20px adds 4px below the descent)

2. line-height only sets the space between lines
  (font-size of 16px and line-height of 4px adds 4px below the descent)

I think the first would make the most sense as a leading-model addition, 
as it’s closest to what CSS does now. Instead of dividing the difference 
and adding to both top and bottom, it just adds the whole difference to 
the bottom.

Thanks,

Alan
