with Western typography,  +-----------------------------
I don't know how relevant it is to other scripts.

I guess this has been discussed before, and there is no
major harm done. How the leading is calculated is only 
relevant when calculating borders or when two different 
blocks meet, as with the subheads simulated above. It 
can be compensating by adding padding-top and negative
padding-bottom, but calculating the right values makes
writing style sheets needlessly complex. We'll probably
be stuck with a "Netscape layout" with every heading an 
appendix to the previous paragraph for a long time to come.
