// AXNode as the node type, that just delegates to an AXTree. The purpose
// of this is so that AXTreeSerializer only needs to work with the
// AXTreeSource abstraction and doesn't need to actually know about
// AXTree directly. Another AXTreeSource is used to abstract the Blink
// accessibility tree.
