Alexander,
You're going at this problem a bit backwards. It seems that you're only
looking at the svn protocol itself, and trying to figure out how svn
works in general. What you need to understand is that the svn protocol
is a direct marshalling of the overall Repository Access (RA) API. You
need to read svn_ra.h and understand all of the "commands" that a client
can send to a server. svn_ra.h is fully documented. Of course, this
also means you'll have to read svn_delta.h, which explains the 'editor'
concept -- the main mechanism that client and server use to describe
tree-deltas to each other.
Once you understand svn_ra.h (there are 3 different implementations of
it for you to study), you'll see that the svn protocol is just one of
those implementations. In fact, it's the most "literal" implementation.
