The abstract interface to features, which may have application-dependent implementation.

Implementations of node array factory, extension value conversion handler, and extension value comparison handler are contained in the XPath implementation class; the corresponding objects may be obtained via class member functions.

It is assumed that every application or library that employs classes of the Xpath namespace will supply the class derived from CXpathImplementation to provide the appropriate implementation of application-dependent features.
