class TPacketDataConfigBase 

/** Base class for the packet configuration classes.

The Context configuration, QoS profile (Requested and Negotiated) and QoS 

Capabilities classes inherit from this class. It is outside the scope of all 

the Packet data classes. 

To allow future configuration structures (e.g. TContextConfigWCDMA, 

TContextConfigPDC, etc.) to be added in such a way that a completely different 

structure may be defined and passed into the same functions as this one, all 

existing configuration structures are derived from this thin base class 

which provides just one function, ExtensionId(). This function returns the 

one protected member variable, iExtensionId. A new structure would define an 

associated new constant to be set in iExtensionId on construction, which would 

then be queried by the TSY prior to unpackaging the structure.
