Remarks
By default only non-abstract embedded elements are addable, with the exception of the extensions. Can be overridden, but it is not recommended to include relationships that are not embeddings, as the explorer makes a general assumption that it is only adding through embeddings and its behaviour is undefined if this is not the case
