Chris,

I do not think that we have to borrow some text from Part 2 and
reformulate it.  Part 4 can simply specify its own restrictions on 
OPC.  

But exactly what is the difference between the first edition Ecma OPC
and ISO/IEC 29500-2:2008?  I am comparing these two documents, but 
I do not quite understand the difference.  "9.1.1  Part Names" has 
been significantly expaned but Appendix A "Resolving Unicode Strings 
to Part Names " existed from the beginning.  One could argue that 
the use of non-ASCII characters is allowed from the beginning.  I 
am totally confused.

Cheers,
Makoto
