        To modify an order to another product plan or update parameters, you
        must specify product request. To specify parameters, you must follow the
        pattern "ParameterName=ParameterType:ParameterValue". For example:

            $ {command} --product-request line-item-id=lineItemId,line-item-change-type=UPDATE,product-external-name=productId,flavor-external-name=flavorId,region=str:us-west-1

        To cancel a product plan-based order, you must specify the product
        request. For example:

            $ {command} --product-request line-item-id=lineItemId,line-item-change-type=CANCEL

        To revert cancellation on a product plan-based order, you must specify
        the product request. For example:

            $ {command} --product-request line-item-id=lineItemId,line-item-change-type=REVERT_CANCELLATION

        To update an order to another quote, you must specify the fields that
        are related to the quote. For example:

            $ {command} --quote-change-type UPDATE --new-quote-external-name quoteId

        To cancel a quote-based order, you must specify the quote change type.
        For example:

            $ {command} --quote-change-type CANCEL

        To revert cancellation on a quote-based order, you must specify the
        quote change type. For example:

            $ {command} --quote-change-type REVERT_CANCELLATION
        """,
