add a new section to Team Central.

Ben:
Thanks for your reply.
Before asking this question I have already read the article you gave,however, what I want is not only a section like the section in Team Central but also a view with the sections,such as "Event log","Team load", that is to say, I want to write my own Team Central plug-in like the RTC has.
I think if I can find the plugin.xml of Team Central I will know how to do clearly, is it a right way?
Many thanks.

Ah I see, this is not possible unless you start subclassing the
TeamCentralView which is not really recommended. You can see the
MyWorkView doing this.

Ben:
I also find it is not a wise idea to write a plug-in like Team Central, so now I decide to add a section into Team Central.
It works and I also add the data I want to be displayed in my section.However, when I open a RTC plug-in's xml I find the code:
<expandableSection>
class="com.ibm.team.workitem.rcp.ui.internal.dashboard.QuerySection"
icon="icons/obj16/sectn_wkitems.gif"
id="com.ibm.magnolia.workitems.views.myOpenWorkItems"
isOpenable="true"
name="%MyOpenWorkItems.name1">
<parameter>multi</parameter>
<parameter>5</parameter>
<parameter>true</parameter>
<parameter>com.ibm.team.workitem.queries.predefined.myOpen</parameter>
<parameter>com.ibm.team.workitem.attribute.priority</parameter>
</expandableSection>

Could you tell me what's the function of parameters(red) ?
Many thanks~
