That was also left as a TODO - the dbxrefs list is normally used for single
identifiers - here it would be "RFAM:RF00177" and "SILVA-SSU:FJ904258"
for consistency with the other parsers. At the time I was undecided on how
to handle any secondary identifier Would you need/want this too? Maybe
as  "RFAM:RF00177:SSU_rRNA_5"?
