Add Examples for Airline Ticketing Flows in XInput RFC

[ravi-prakash-v]

Description

Due to some new use cases that heavily involve form submissions, it has been decided to improve the functionality of the XInput schema. Currently, the XInput schema only allows single forms to be transmitted from a BPP to the BAP.

The updated draft of the XInput schema can be found in https://github.com/beckn/protocol-specifications/blob/v1.2.0-draft/docs/BECKN-007-The-XInput-Schema.md

To understand these flows, we need to add examples that cover various use cases.

Feature Request

In the Example Workflows section of the above document, add an example workflow for an Airline Ticketing containing two sub-flows,

• Booking
• Web Check-in

Goals

• Complete airline booking flow
• Complete web check-in flow

Expected Outcome

• A developer working on a airline ticketing BPP should be able to understand how to implement Booking and Web Check-in flows using beckn.
