Well, I don't know. :-) I only try to find a solution for the 'aliases'
problem other people request, using generic SVN techniques.
At first, it makes the behavior identical to CVS: If you tag something
and checkout the tag again, you get _precisely_ the same thing that you
had when you tagged. "svn status -v" and "svn info" will give the same
output as before the tag. It would even anticipate that the repository
revision counts over time: Using "conventional" SVN tags one ends
checking out the tag directory @10 or @15 or @1500 if the repository was
updated a couple of times. In the proposed tag walk-back way you would
always end up at /repos/trunk @5-7. That's what I'd call a real tag (if
I needed such :-)).
And all that with the added value of versioned tags which you don't have
in CVS.
