非 Null = 次要 XML 索引。Nonnull = Secondary XML index.

非 Null 是主要 XML 索引的自我聯結參考。Nonnull is a self-join reference to the primary XML index.

否則,就是用來建置次要選擇性 XML 索引的升級路徑識別碼。Else, the ID of the promoted path over which the secondary selective XML index is built. 這個值與 sys.selective_xml_index_paths 系統檢視的 path_id 值相同。This value is the same value as path_id from sys.selective_xml_index_paths system view.
