magento/magento2#: Incorrect annotation in the Magento/Framework/MessageQueue/etc/queue.xsd schema

[atwixfirster]

Description (*)

Per my opinion Magento/Framework/MessageQueue/etc/queue.xsd schema contains incorrect annotations.

When you configure Message Queue via RabbitMQ storage (amqp connection type) then annotation is correct because developer specifies all details in the files

• communication.xml
• queue_consumer.xml
• queue_publisher.xml
• queue_topology.xml

and Magento\Framework\Amqp\Exchange::enqueue reads a configuration data from the communication.xml file.

However, when a developer wants to process Message Queue via MySQL storage (db connection type) then it has to use queue.xml because Magento\MysqlMq\Model\Driver\Exchange::enqueue reads configuration data from that file.

Hi @atwixfirster. Thank you for your contribution
Here is some useful tips how you can test your changes using Magento test environment.
Add the comment under your pull request to deploy test or vanilla Magento instance:

• @magento give me test instance - deploy test instance based on PR changes
• @magento give me 2.3-develop instance - deploy vanilla Magento instance

For more details, please, review the Magento Contributor Guide documentation.

Since DB-based message queue still require this file (https://github.com/magento/magento2/blob/2.3/app/code/Magento/MysqlMq/Model/Driver/Exchange.php#L44) I believe it's a good catch.
Also, a similar practice of using an explanation of deprecation in XSD schemas can be found here
