How do you configure the spring integration poller after XSD changes have invalidated the fixed-delay and fixed-rate attributes?

Original xml:

<int:poller default="true" task-executor="stepTaskExecutor" fixed-delay="1000">

The fixed-delay attribute is no longer legal, and fails XML parsing in the (eclipse) IDE.

Alternative configuration: An alternative suggested elsewhere (including https://docs.spring.io/spring-integration/docs/2.0.0.M3/spring-integration-reference/html/samples.html):

<!-- Globally scoped Spring Integration bean resources -->
<!-- see https://stackoverflow.com/questions/73450768/how-to-configure-channels-and-amq-for-spring-batch-integration-where-all-steps-a/73455134#73455134 -->
<!-- see https://stackoverflow.com/questions/28625635/attribute-fixed-rate-is-not-allowed-to-appear-in-element-intpoller -->
<int:poller default="true" task-executor="stepTaskExecutor">
    <int:interval-trigger interval="1000"/>
</int:poller>

This passes the XML parsing in the IDE, but fails at runtime

Log snip:

Caused by: org.xml.sax.SAXParseException: cvc-complex-type.2.4.a: Invalid content was found starting with element 'int:interval-trigger'. One of '{"http://www.springframework.org/schema/integration":transactional, "http://www.springframework.org/schema/integration":advice-chain}' is expected.

Use Spring Tool Suite (eclipse), or add the spring tools plugin to your eclipse so that the schema is loaded from the jar file instead of from the internet.
