I'm not certain that I understand your point -- a document cannot
invent new architectural forms for an existing base architecture.  
It is true that since architectural forms allow multi-generational
inheritance, you can invent a new base architecture that is derived
from an existing base architecture (just as you can derive a new class
from an existing one in Java).
All the best,
