I will add the native primary key to the messages.

Can you be more specific here? My understanding is that in the MAD data model, both the base address and unit address tables have "native primary keys". If that's correct, then A5 is ambiguous.

This is a MAD artifact - DBI probably won't want it.
But let me explain the purpose.
A MAD "address" is represented using the concept of a base address and a unit address.
A base address always has one corresponding unit address.
There may be additional unit addresses or not.
If the base tag is marked true, then this unit information is directly associated with the base address.
If the base tag is marked false, then this unit information is not directly associated with the base address.

Can you elaborate on what is meant by "directly associated" in this context? Are there additional associations possible between a unit address and a base address (besides "not direct")?
