RE: Version merging questions

I guess I think of it a little different. There is an "un-modifiable" list
and a "modifiable" one. The first is managed by the server and represents
what the server knows to be correct. The second is managed by the user and
could be totally wrong. 
I think both of our points are valid and true and that we are essentially
saying the same thing.
Cheers,
Chris

		 What I believe we have specified to date is that there
are "conceptually"
		 two revision graphs. There is a graph that the server
maintains and
		 asserts is correct and there is a graph that is specified
by the client
		 that may be incorrect.
		I disagree. It is not an issue of correctness or
incorrectness, but
		rather an issue of modifiable and non-modifiable predecessor
		relations. The reason to maintain a tree of non-modifiable
		predecessor relations is just a recognition of the fact that
many
		implementations of branching and delta storage make it very
expensive
		or even impossible to move a version from one branch to
another.
		Logically, the predecessor in this tree is no more "correct"
than
		the modifiable predecessors created by the MERGE method.
