+/**
+CSuplMessageBase is an abstract class providing a base definition for SUPL
+messages either received or constructed for sending. Concrete classes derived 
+from this class represent each of the supported SUPL message types, and provide
+methods for accessing and setting their member parameters.
+
+When building outgoing messages, the constructor must be called with 
+aIsOutgoingMessage set to ETrue. This results in the internal data members 
+necessary for building and encoding an outgoing message.
+
+For received messages, the SUPL ASN1 Decoder object (see csuplasn1decoder.h)
+calls SetDecodedData(), passing the decoded data structures (ownership is passed
+immediately on entrance to this method). Note that these data structures are 
+defined by compilation of the SUPL definition using a third party ASN1 compiler
+and therefore do not conform to standard Symbian naming conventions. 
+
+Types encapsulating common parts for operation within the SUPL Protocol Module
+are described in file suplmessagecommon.h
