Abstract:
 
    Base PrintCapabilities handler class implementation. This class provides common
    PrintCapabilities handling functionality for any feature that requires
    PrintCapabilities handling. A feature specific handler can derive from
    this class to get feature unspecific XML handling functionality.
 
--*/
 
 
//
// Note on handling missing DOM nodes:
//
// Convert MSXML's S_FALSE to E_ELEMENT_NOT_FOUND. This allows clients to
// use the SUCCEEDED macro more effectively.
//
// E_ELEMENT_NOT_FOUND should not be propogated as an error to the
// filter pipeline or config module - treat as though the requested feature
// has not been enabled.
