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.
