A treeitem should be placed inside a treechildren element and should contain treerow elements. The treeitem can be clicked by the user to select the row of the tree. The treeitem contains a single row and all of what appear to the user as that row's descendants.
In a template condition, you should use a treeitem instead of a content element when the dont-build-content flag is specified. Set the uri attribute to the variable name to bind to a content node during matching.
More information is available in the XUL tutorial.
