A BUFR message is made of some headers and a data section. The structure of the data section is defined in the headers by a sequence of BUFR descriptors, which are sequences of six digit numbers having a particular meaning (see BUFR tables). To modify this sequence of descriptors ecCodes provides the key unexpandedDescriptors.
