Abort SDO transfer and sending response

[jafem]

Is there a reason why only the SDO timeout response is sent in COCSdoAbort when a SDO transfer is aborted?

static void COCSdoAbort(CO_CSDO *csdo, uint32_t err)
{
    CO_IF_FRM frm;

    /* store abort code */
    csdo->Tfer.Abort = err;

    /* send the SDO timeout response */
    if (err == CO_SDO_ERR_TIMEOUT) {
        CO_SET_ID  (&frm, csdo->TxId        );
        CO_SET_BYTE(&frm, 0x80,           0u);
        CO_SET_WORD(&frm, csdo->Tfer.Idx, 1u);
        CO_SET_BYTE(&frm, csdo->Tfer.Sub, 3u);
        CO_SET_LONG(&frm, err,            4u);
        CO_SET_DLC (&frm,                 8u);

        (void)COIfCanSend(&csdo->Node->If, &frm);
    }
}
