A Composite TextMap Propagator is a Propagator that performs run multiple TextMap Propagators in a specified order.

An example of creating a Composite TextMap Propagator to inject and extract Baggage and TraceContext:

  Propagator = otel_propagator_text_map_composite:create([trace_context, baggage]),
  otel_propagator_text_map:extract(Propagator, Carrier)
