[Springframework-developer] xml dtd addition for bean id reference

[Colin S. <col...@ex...>]

The recent switch in AbstractAutoProxyCreate which forced me to switch 
some BeanNameAutoProxyCreator configs from something like
...
     <property name="interceptorNames">
      <list>
        <ref bean="hibInterceptor"/>
        <ref bean="matchAllTxInterceptor</ref>
      </list>
    </property>
...

to
...
    <property name="interceptorNames">
      <list>
        <value>hibInterceptor</value>
        <value>matchAllTxInterceptor</value>
      </list>
    </property>
...

got me thinking that the former did have the advantage of being much 
easier to validate without getting the actual user of the properties 
(the postprocessor in this case) involved. That is, in the case of a
   <ref local="xxx" />
the xml processor can do it, while
   <ref bean="xxx" />
can be validate by the loader or something like an Eclipse plugin. But

    <property name="interceptorNames">
      <list>
        <value>something</value>
      </list>
    </property>

can only be validate by the user of that property.  So how about we add 
another element which is used to produce a text value which is a bean 
id. That is:
    <property name="interceptorNames">
      <list>
        <beanid bean="a-local-or-external-bean"/>
        <beanid local="a-local-bean"/>
      </list>
    </property>

The latter beanid element would be checked by the xml processor. The 
former would be checkable only by the loader or by something like an IDE 
plugin.

What does everybody think?
