 Provides an interface for writing serialized XML data to a stream.  This

 interface should be implemented by client applications when the

 RXmlEngDocument::SaveL() method is used to serialize XML data to a stream.

 No ownership is transferred by RXmlEngDocument::SaveL(), thus an object

 of the implementing class should be freed after use.
