William,

It is  potentially dangerous ground.
But ...

-  Archetypes express what can be documented about a specific topic.
Since such a 'Real Archetype' can or will consist of re-usable  
patterns, 'Real Archetypes'  consist many times of a collection of sub- 
archetypes that express recurring patterns of documentation.
In other words archetypes can and will be nested.
And there must be a way to specify what archetypes are part of the  
ensemble at what spots.

- It will create the problem for Archetype Governance.
We need to have rules and ways to manage and enforce them.
This needs a tool.
Ocean Informatics, for this purpose, has developed the Archetype  
Knowledge Manager.
