  A member in the structs below is said to "primary" if its content
  cannot be inferred from other members in any of structs below; a
  member is said to be "derived" if its content can be derived from
  other members. For example, AjOVarBcf::str is primary as this comes from
  the input data, while AjOVarBcf::info is derived as it can always be
  correctly set if we know AjOVarBcf::str. Derived members are for quick
  access to the content and must be synchronized with the primary data.
