/**
* This is the private API which is used to extract per tenant objects (catalog, overdue, invoice templates, ..)
*
* Some of these per tenant objects are cached at a higher level in their respective modules (catalog, overdue) to
* avoid reconstructing the object state from the xml definition each time. As a result, the module also registers
* a callback which is used for the cache invalidation when the state changes and the operation occurred on a remote node.
* For those objects, the private api is called from the module.
*
* Some others (invoice templates,...) are not cached (yet) and so the logic is simpler.
*
* The api can only be used to retrieve objects where no caching is required.
