Er, sorry, I did misread.

The fundamental difference is that there's no concept of deltas (in
the RA protocol, etc) for properties in Subversion. Thus no
difference between "change property" and "set property". "svn import"
can only add files, not edit them... but the change_node_prop call
looks the same for both.
