TreeNode's from XML File - ToolTip

not sure this is the right place for this, but here goes....

I got a IE Webcontrol TreeView on my page.

Created a simple xml file, and bind it to the treeview to populate the nodes

Code:

---

<TREENODES>
  <TreeNode text="country">
          <TreeNode text="China" >
                  <TreeNode text="Beijing"/>
                  <TreeNode text="Shanghai"/>
                  <TreeNode text="Hunan"/>
          </TreeNode>   
    <TreeNode text="USA"/>
    <TreeNode text="Australia"/>
    <TreeNode text="France"/>
  </TreeNode>
</TREENODES>

---

Code:

---

    //bind the treeview to the sample xml file
    myTreeView.TreeNodeSrc = "xml/treenode.xml";
    myTreeView.DataBind();

---

Is it possible to include a node's tooltip text in the xml file? something like ....

Code:

---

<TreeNode text="USA" tooltip="this is a test"/>

---

the latter does not work of course

....anyone?
