/**
* Gets a partial reference to the document identified by the given type and identifier
* without actually loading it, if the document is not yet loaded.
*
* The returned reference may be a partial object if the document is not yet loaded/managed.
* If it is a partial object it will not initialize the rest of the document state on access.
* Thus you can only ever safely access the identifier of a document obtained through
* this method.
*
* The use-cases for partial references involve maintaining bidirectional associations
* without loading one side of the association or to update a document without loading it.
* Note, however, that in the latter case the original (persistent) document data will
* never be visible to the application (especially not event listeners) as it will
* never be loaded in the first place.
*
* @param string $documentName The name of the document type.
* @param mixed $identifier The document identifier.
* @return object The (partial) document reference.
