Be able to define tx:annotationdriven order attribute as a ref [SPR-7342]

[spring-projects-issues]

David J. M. Karlsen opened SPR-7342 and commented

It would be nice if the order attribute could refer to a value as a ref
I have the aspect orders defined as constants on an interface

and would like to refer to it like this
<util:constant static-field="util:my.comp.myproduct.core.util.aop.AspectOrder.TX" id="txOrder"/>
<tx:annotation-driven order="-2147483647" />

Tried to express this as an el expression instead, but I get

Caused by: org.springframework.beans.factory.xml.XmlBeanDefinitionStoreException: Line 69 in XML document from class pat
h resource [resources-context.xml] is invalid; nested exception is org.xml.sax.SAXParseException: cvc-datatype-valid.1.2
.1: '#{ T(com.edb.payment.pays.core.util.aop.AspectOrder).TX * 1 }' is not a valid value for 'integer'.
        at org.springframework.beans.factory.xml.XmlBeanDefinitionReader.doLoadBeanDefinitions(XmlBeanDefinitionReader.j

based on

<tx:annotation-driven order="#{ T(my.company.myproduct.core.util.aop.AspectOrder).TX }" />

AspectOrder is an interface with constants.

Shouldn't this work?

This works fine along with #15514 now, with the 'order' attributes in our namespaces accepting tokens and therefore also EL expressions.
