However, as indicated in the original message, there are times when the
behaviour
you want is to use the new version in the second document. That is an
instance of
true "sharing". At other times, you want to remain linked to the
original, so that the
node diverges into 2 separate versions.
That creates a requirement, when reusing a node, to either "create a
live link" or "use a copy". The existence of two possiblities then
predicates the need for a default option and possibly a configuration
option to set the default.
