Among things that are not entirely clear, let us start with WHY SC4 
should want a "Technical corrigendum" that /adds a feature/ to Edition 
1.  The long-standing practice of SC4 is to provide the ASN.1 
identifiers in an Annex to the specification that defines the schemas.  
I can only assume that the intent of this proposal must be to provide a 
means of explicitly making those identifiers part of the schemas 
themselves.  Such a change in practice would imply a host of TCorrs to 
the family of SC4 published models -- a lot of formal paperwork to 
provide syntax for what could be an implementors' agreement for an 
implementation convention.  I suspect that the intent is rather to do 
the corresponding TCorrs to one or two APs whose implementors care. 

At the same time, I have to ask WHY NOT make the change to EXPRESS Ed2.  
Is there some reason to suppose that the "one or two APs" of interest 
are not valid EXPRESS Ed2 schemas?

It appears that Phil and I have come in in the middle of this movie.  
Can someone please summarize the plot thus far?

STEP CAD files with externally referenced shape are now more widely used, and several groups are looking at splitting other types of AP data across multiple files (PMI, kinematics, machining process, cutting tools).  To date, this has been handled at the information model level, but there may be infrastructure things that WG11 can do to help.  T24 and LOTAR have been invited, other groups with an interest are welcome.
