0007   Description: Used as part of tests that ensure the FEDRawDataCollection
0008   data format can be persistently written and in a subsequent process
0009   read. First, this is done using the current release version for writing
0010   and reading. In addition, the output file of the write process should
0011   be saved permanently each time the FEDRawDataCollection persistent data
0012   format changes. In unit tests, we read each of those saved files to verify
0013   that the current releases can read older versions of the data format.
