Indicate a fulfillment without a document and part

[rolandkla]

Context

A fulfilment contains ticket information such as the control number, status and its related document(s). It is possible that an OSDM provider returns a fulfilment (because of the control number and status) but it does not return any documents or parts.
This is the case where a distributor generates the documents on behalf of the provider.

In this case, when an OSDM client fetches a booking it is not aware if the documents/parts are yet to be generated or if they will remain absent on purpose. This could lead to clients polling without result.

Potential solution
Extending the fulfilment object with an indicator to inform the client that documents/parts should be expected, then the client knows if it has to wait for documents or not.
This can be achieved by introducing a status or a property indicator.

Proposal:

add an indication "ContentComplete" in Fulfillment:

• false: content or additional content (documents or fulfillment parts) will be provided.
• true: content (documents or fulfillment parts) provided iscomplete. If no content is included this is intentional.
