AdditionalDocumentReference is currently injected right after DocumentCurrencyCode.
However, in 15.0, OrderReference is implemented and then, AdditionalDocumentReference is no longer injected at the right place.
To fix this, we inject now this field just before AccountingSupplierReference that must be always there and Signature is not implemented.
