 // may be computed dynamically, but maintains the properties that
 // it's a strict tree, it has a unique id for each node, and all
 // of the accessibility information about a node can be serialized
 // as an AXNodeData. This is the primary interface to use when
 // an accessibility tree will be sent over an IPC before being
 // consumed.
