  <camelContext xmlns="http://camel.apache.org/schema/spring">
    <route>
      <from uri="seda:foo"/>
      <to uri="mock:results"/>
    </route>
  </camelContext>
</beans>

1. Open VSCode with attached XML
2. List down element suggestion after line 17 by typing <.
3. Select export element and add uri parameter to it since its required.
4. It throws an cvc error.

It should not list export if it's after route element as per XSD, since it has to honor xsd:sequence.
