Hi,

I've just realized that putting more than one parameter with the name 
supportedEventType in the parameters element will not work correctly. 
Take a look at the example (taken from the test rrd metadata config file):


   <nmwg:metadata id="meta1">
       <netutil:subject id="subj1">
           <nmwgt:interface>
               <nmwgt:hostName>test-hostName</nmwgt:hostName>
               <nmwgt:ifAddress type="ipv4">10.1.2.3</nmwgt:ifAddress>
               <nmwgt:ifName>test-0</nmwgt:ifName>
               <nmwgt:ifDescription>test descripyion</nmwgt:ifDescription>
               <nmwgt:direction>in</nmwgt:direction>
               <nmwgt:authRealm>TestRealm</nmwgt:authRealm>
               <nmwgt:capacity>1000BaseT</nmwgt:capacity>
           </nmwgt:interface>
       </netutil:subject>
       <nmwg:parameters>
           <nmwg:parameter 
name="supportedEventType">utilization</nmwg:parameter>
           <nmwg:parameter 
name="supportedEventType">packet_loss</nmwg:parameter>
       </nmwg:parameters>
   </nmwg:metadata>


Doing this we want to use the same metadata/subject for two metrics (to 
not repeat metadata element for different eventType elements). 
Unfortunately the java class representing parameters element 
(src/org/ggf/ns/nmwg/base/v2_0/Parameters.java) uses HashMap to store 
parameter elements. This map can not keep two parameter elements with 
the same name.

Jason, could you take look at this? What's your opinion on this? Others?
