    How can I use the selection mechanism to implement ATK cut/paste protocol?

Your question is not specific enough to provide a real answer.  There are
probably lots of ways it could be implemented.  But, without knowing what
all of the requirements are, it's probably impossible to know if any of them
are actually adequate.  You haven't given any indication of how non-ATK
clients should interact with ATK clients at the UI or semantic level, you
haven't said anything about lifetime of the items.  There may be other
things you haven't specified that are crucial (I haven't thought about
it too hard).
