In that case, in the streaming example would this tree of children (stored in map_?) be complete? I see in the idref::get() method it performs root_()->lookup() which would assume that the correct root container can be referenced in root_() and that lookup() can find the matching ID element from map_.  Considering that in the streaming code the type_ objects are often discarded, would keeping a "shell" of the root element solve this problem? Or do I need to have the complete tree in memory for it to work correctly?

Thank you and regards,
Laurence

Yes, that's correct.
