 public function detectObsoleteConnections(Schema $schema, ObjectFetcher $objectFetcher)
 {
     // CHANGED objects can have persisted relationships that don't exist in the parsed dataset.
     // Such persisted relationships must be removed. This implies that either
     //   a. nothing special needs to be done, or
     //   b. persisted connected objects must be 'patched', i.e. their foreign key must be set to NULL, or
     //   c. persisted connected objects must be deleted, or
     //   d. a persisted link (mant-to-many relationship) must be deleted.
     // Option a. is the case when the CHANGED object holds the foreign key and if is NOT an owner of the
     // connected object, or when the connected object is present in the set of ParsedObjects.
     // Option b. applies to connected objects that are not in the set of ParsedObjects. Such connected objects
     // must be added as CHANGED ParsedObjects and filled with all existing property values, except for the
     // foreign key.
     // Option c. applies to situations where the CHANGED object is the owning entity. In this case the existing
     // connected object must be added to the set of ParsedObjects and marked as DELETED.
     // Option d. is similar to option c, but the connected object is a LinkEntity. LinkEntities cannot be referred
     // to by a single id and therefore cannot be dealt with via ParsedObjects. Creating or deleting LinkEntities is
     // done in ParsedObject::establishLinks().
     //
     // Note that ParsedObjects marked as 'touched' are not modified themselves, but they may have modified
     // relationships. These ParsedObjects must be treadet the same as CHANGED objects here.
     //
     // So these are the steps to be taken:
     //   1. loop over the CHANGED and 'touched' ParsedObjects
     //   2. per object, loop over the relationships, ignoring many-to-many (link) relationships
     //   3. check if the entity of the object is NOT the foreign key entity in the relationship
     //      and check if the object is owner of the connected object
     //   4. if either is the case, then see if the parsed data specifies a connection for this relationship
     //   5. if NOT, then add the connected object to the set of ParsedObjects
     //   6. if the connected object is NOT an owner, then fetch its id and mark the newly created ParsedObject
     //      as DELETED
     //   7. if the connected object is the foreign key entity, then fetch and set its id and all its properties
     //      (except for the foreign key) and mark the newly created ParsedObject as CHANGED
