Actually, DeltaV has several models that it encompasses. One of those
matches SVN precisely.
(not much of a surprise given that a certain SVN developer had input to the
 DeltaV specification... :-)

Right. SVN 2.0 will be my playground for increasing DeltaV compatibility on
both sides. The client will have various fallbacks and codepaths to enable
working with different servers (optimized for the SVN server). The server
will support more of the DeltaV spec, enabling more clients to work with it,
using whatever strategies they may prefer.

"exactly" might not be the proper word :-) However, I have noted in the
document where the doc may be out of date or not completely filled in.
