Doug,

you may remember my request for something similar, via libclang. To be 
able to extract inline documentation from source code, I also need to 
find the source range not only for a particular declarator, but also the 
entire declaration. Right now there is no way to get to that via 
libclang, as declarations aren't represented by cursors.

Thanks,
         Stefan
