Re: [Springframework-developer] one more thing about bean metadata

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

   I am also wondering if it is possible make default xml parser to 
handle nested value, list, set, map and props tag (for simple/string types)?

   Value element would be more convenient then value attribute e.g. 
multiline CDATA.

   Lists are also quite common use case. E.g. somehow made up example:

   <meta key="org.javatx.auth.Role">
     <list>
       <value>Admin</value>
       <value>Observer</value>
     </list>
   </meta>

   So, as props. Here is an example:

   <meta key="org.javatx.Transactional">
     <props>
       <prop key="timeout">1000</prop>
       <prop key="propagation">required</prop>
       <prop key="isolation">serializable</prop>
     </props>
   </meta>


   Thanks

   Eugene
