The background and foreground color should be defined for the body, but 
mostly is not defined. In reality, I mean.

I do calculate a contrast ratio and for that purpose I need background 
and foreground color. Currently, if I can't determine a background color 
for a particular element then I do skip contrast ratio calculation.

I am working on https://www.aslint.org/. The code is not public yet, but 
I have a plan to publish it.
