Detailed Description

A DomItem that owns other DomItems and is managed through a shared pointer.

This is the unit of update of the Dom model, only OwningItem can be updated after exposed, to update a single element one has to copy its owner, change it, and expose an new one. The non owning contents of an exposed OwiningItem can safely be considered immutable, and pointers to them must remain valid for the whole lifetime of the OwningItem (that is managed with shared_ptr), only the sub OwningItems might be change. The OwningItem has a mutex that controls it access (mainly for the errors, observers, and sub OwningItems), Access to the rest is not controlled, it should either be by a single thread (during construction), or immutable (after pubblication).
