-Each object can be associated with a L<File::KDBX> database or be disassociated. A disassociated object will
-not be persisted when dumping a database. It is also possible for an object to be associated with a database
-but not be part of the object tree (i.e. is not the root group or any subroup or entry). A disassociated
-object or an object not part of the object tree of a database can be added to a database using one of:

# OR move an existing entry from one database to another:
- $kdbx->add_entry($entry->remove);

+
+=attr uuid
