For starters, the delete verb is reserved for node deletion. I would
recommend against overloading it in the non-owner namespace to mean
something else entirely.
Futher, I'm wondering if this is a publisher use case, or an owner use
case. I'd say it is an owner use case, so maybe we could add something
to <purge/> to specify which items to purge, retaining the default of
purging all items in the node. Not sure what to do with purge
We might also consider introducing the <retract/> verb in the owner
namespace that means silent retraction.
