Logical this is called a self-referential foreign key. For example, if you want rows of a table to represent nodes of a tree structure, you could write CREATE TABLE tree ( node_id integer PRIMARY KEY, parent_id evaluated, passing the XML value document_expression as its context item, to obtain a set of XML nodes. These nodes are what xmltable transforms into output rows. No rows will be produced if the docu- ment_expression
