dynamic-menuitem ina D2 4.1 Plugin and conditions

BTMSoftware

I have a question regarding dynamic menu items in a D2 4.1 Plugin I'm developing

so far, I can populate the item with multiple entries in them, depending on the config.

I have a context menu (defined in the MenucontextDelta.xml in my plugin) as shown below

<dynamic-menuitem id="mydynMenu" class="com.emc.btm.webfs.menu.dynamicmenus.MyMenu" />
     <condition class="com.emc.d2fs.dctm.ui.conditions.interfaces.IsConnected" />
     <condition class="com.emc.d2fs.dctm.ui.conditions.objects.IsQuery" equals="false" />
     <condition class="com.emc.d2fs.dctm.ui.conditions.actions.CanView" />
     <condition class="com.emc.d2fs.dctm.ui.conditions.typeparts.IsDocument" showifinvalid="true" />
     <condition class="com.emc.d2fs.dctm.ui.conditions.objects.HasContent" showifinvalid="true" />
</dynamic-menuitem>

this has already some conditions which are global to all the menu entries I will add in my MyMenu class.

So far so good.

Now the question is that still in my class, when I create new menu entries (depending on values in a registered table), I need to apply different conditions on these new entries

XmlNode node = result.appendChildNode("menuitem");
node.setAttribute ("id", "myid");
node.setLabel ("label", "my label");
node.setAttribute ("action", "myAcvtion()");

Now, it comes.

How can I had a condition, using setAttibute ???? creating a child node ?

Any idea
