Hi,
I agree with the goal.
Although I don't have all the details in memory, why not fully build the
domain (ie building pal/sal stubs) from libxc ?
If this is doable, I think it should be cleaner.
[This is just an idea to be discussed. If we agree this is cleaner and doable
then someone might implement it. The only drawback might be code duplication]
