Parser.parseFlowSequenceEntry

flow_sequence ::= FLOW-SEQUENCE-START (flow_sequence_entry FLOW-ENTRY)* flow_sequence_entry? FLOW-SEQUENCE-END flow_sequence_entry ::= flow_node | KEY flow_node? (VALUE flow_node?)?

Note that while production rules for both flow_sequence_entry and flow_mapping_entry are equal, their interpretations are different. For flow_sequence_entry, the part KEY flow_node? (VALUE flow_node?)? generate an inline mapping (set syntax). Parse an entry in a flow sequence. If first is true, this is the first entry.
