Correct condition, it shall be inverted.
Fix wrong name open_order.
No need to archive - some other magic does it already.

Also detect tag in add_kw and relock on it.

Edit only hosting delivery, as this one does not come from simulation.

Person_updateOpenOrder will be single point to manipulate open orders.

Expose the path, as method is used during reindexation, so there might be no
way to find the object by reference.

Also update consistency checking.

connection_xml was not correctly validated.
connection_xml and sla_xml are optional, so their dict can evaluate to None or {},
which is False.

Subscription movements are not built for now.

But whenever it is set, it shall be correct XML.
