Should the implementer net be wider that just SMIME?

I believe that this is useful independent of where tools draw 
the line.
This is an advantage of putting more data into a single location for 
people to read rather than having to go through the entire 
document for 
the same data.

I've been thinking about this, and I agree.  It really would 
help implementors to link all of this information together 
with unambiguous ASN.1, but it does lead to a compatibility 
problem.  We would no longer be using the same definitions as 
X.509.  The new ones would include this additional information 
to aid implementors, and generate exactly the same bits on the 
wire.  I'm not sure the incompatibility is worth it.

Implementors need to speak up here?  The structures proposed 
by Jim would replace tables (or some other structure chosen by 
the implementor).  Are implementors going to embrace the 
approach offered by Jim?
