 * after this node. If still not found, we will check if this node is
 * already indented from its parent. If yes, this node's indentation will
 * be used. Otherwise, the parent node's indentation plus one indentation
 * will be used. If this node is null or it's a document node or it's a
 * first level node (node's parent is a document node) the default empty
 * string will be returned as the indentation.
