XQDataFactory

This interface represents a factory to obtain sequences, item objects, and types, which when obtained are independent of any connection.

Some of the methods in this interface create element, document, or attribute nodes. DataDirect XQuery creates untyped instances of these nodes.

Table G-2 describes how DataDirect XQuery supports the methods of the XQDataFactory interface.
