That was Jens' library. The version I have supported these hooks (which were overridden for specific formats):

void start_sequence(std::size_t) { os << "["; }
void start_sequence_element() { }
void separate_sequence_elements() { }
void end_sequence_element() { }
void end_sequence() { os << "] "; }

void start_struct() { os << "{"; }
void separate_struct_members() { }
void end_struct() { os << "} "; }

void start_value() { }
void end_value() { os << " "; }

Those seemed sufficient for HTML, XML, and other nested data structures in addition to various flavors of CSV and similar formats.
