[occi-wg] Question about Compute instance action

[Ralf Nyren]

Yes, agreed on the non-intuitive part :)

Is it provider specific what happens if you http-delete a running Compute
instance? It could be equivalent to the stop-terminate case...

Using Actions to Create/Delete Resource instances seems to push to usage
of actions a bit to far IMO.
