We extract the data in field 'ZZA' in subfile 'ZZ', undoing the base encoding:
We now decompress with CBOR-LD to get the original JSON-LD VC to be
verified. Again, the parameters are associated with CBOR-LD
registry entry 100.
The ID-to-term mapping that should result from processing the contexts and assigning
integer values to context terms is as follows. Note that this is the inverse of the map
constructed during compression.
