There really aren't any, the demand just isn't high enough to permit me to 
spend time on that. I did spend a lot of time ensuring doxygen documentation 
could be generated for all of the APIs across all of the libraries, but 
that's as much as I can do when the total number of people asking is less 
than one hand's worth.

I will say that it's a very bad idea to "modify" the SP. The system is full 
of extension points, and you should be limiting work to extensions, or you 
should ask for (or contribute, certainly) changes to meet needs that can't be 
addressed by those extension points.

There's also a very limited sample extension "project" inside the Windows SDK 
package on the download site in the win32 and win64 directories, and plenty 
of existing plugins to copy from.

Most of the extension points are documented functionally within the SP 
documentation in terms of how you configure the different components, so 
that's one source of information on what the pieces do. So the SP config 
reference is useful in this regard, but obviously that's not a substitute for 
real architecture or design material.
