[Doxygen-develop] API Doc of Doxygen Parse Tree available ?

[Binsan <bk...@da...>]

I am trying to implement a new output generator by modifying the
RTFGenerator. But I am having trouble understanding the parsing mechanism. 

As I am lost many times tracing the code, I wonder if there is any extra
documentation for developers (besides that already present in the source
code) of the structure of the DocNode and its children.

Any other documentation for developers?
