What your describing is much simpler in svn than in CVS, but what you
need is a paradigm shift. Your current workflow uses tags rather than
a branch since branching in CVS is a pain. In svn what you would do is
create an iteration1 branch rather than a tag. Tags in svn parlance
are read only, whereas branches are not.

Now the way you would handle the bug fixes will vary according to your
development philosophy. In subversion itself all development occurs on
trunk, and then changes are merged selectively onto the release
branches. It might be more natural for your group to do the bug fixes
on the branch and then merge those changes back to the trunk if they
are needed (i.e the bug has not already been fixed there due to other
changes).

Either way viewing iteration1 as a branch rather than a tag will make
applying svn to it more natural.
