I had this problem when implementing another companies proprietary
communications protocol, that we needed to communicate with.
The physical devices were picking-robots.
All messages had a common headers and then message specific fields.
And they had to have certain functions. To_String, Save_to_Database,
Send, etc.
Since I had complete control over the implementation, I
ended up using inheritance from an abstract type.
Some functions of the abstract type were implemented,
and others - to specialized for the inherited type -
was declared abstract.
