Where is this grammar?

Can this be repeated? There might be more than one key for a config_item.

What's the use of <entry>?

>         <key> Key </key>
>         <value> Value </value>
>       </entry>   
      </config_item>                    is missing here.

>   </config_item>
> </configuration>
