[Springframework-developer] once again on bean metadata

[Eugene K. <eu...@pl...>]

   I updated SPR-1711 [*] that is requesting support for bean metadata 
and attached implementation of custom namespace handler and bean 
decorators that allow to declare lists and maps of string as bean 
attributes (test and examples are in the archive attached to that jira 
issue).

   For example:

   <bean id="foo">
     <meta:list name="testList">
       <meta:value>value1</meta:value>
       <meta:value>value2</meta:value>
     </meta:list>
     <meta:map name="testMap">
       <meta:entry key="key1">value1</meta:entry>
       <meta:entry key="key2">value2</meta:entry>
     </meta:map>
   </bean>

   I wonder if something like this can be incorporated into Spring code?

   Thanks

   Eugene
