Handle passing the token through an event element.

Start Event

A BPMN start event can have the following BPMN contents:

<bpmn:startEvent id="StartEvent_1" name="START" camunda:initiator="HTTP">
  <bpmn:outgoing>SequenceFlow_0u2ggjm</bpmn:outgoing>

  <bpmn:extensionElements>
    <camunda:formData>
      <camunda:formField id="username" label="Username" type="string">
        <camunda:validation>
          <camunda:constraint name="username" config="required" />
          <camunda:constraint name="password" config="required" />
        </camunda:validation>
      </camunda:formField>
      <camunda:formField id="password" label="Password" type="string" />
    </camunda:formData>
    <camunda:executionListener class="bpmn.event.start.listener" event="start" />
  </bpmn:extensionElements>
</bpmn:startEvent>

This node can be represented as the following Elixir token:

{:bpmn_event_start,
  %{
    id: "StartEvent_1",
    name: "START",
    outgoing: ["SequenceFlow_0u2ggjm"],
    inputs: [%{"username"=>"user", "password"=>"password"}],
    definitions: [{:error_event_definition, %{}}]
  }
}
