[step-manufacturing] Reminder final call and report of AhG3 on UUID's

[Martin Hardwick]

Tom,

I wish I could stop you.

You are about to repeat a mistake previously made with EXPRESS. Namely, 
making it infinitely complex for little end user benefit.

After the EXPRESS toolkit industry was mortally wounded we tried to limp 
on for ten years but eventually had to exit.

I hope the same will not happen for STEP implementation but am not 
confident. Maybe it will get fixed before you go too far because the end 
user requirement is stronger.

The AhG3 proposal allows us to diverge into an information model 
solution (ISO 10303), and an IT solution (ISO 23247).

I prefer the IT solution because it keeps the UUID's, and the 
information model separate, and because it has the resources  of a large 
industry.

The RFC 4122 DiD proposal is a good one because the UUID's can be 
managed independently of the data. Not everyone needs to be a Part 21 
expert.

Martin
