OPC has interleaving.  Should it be dropped? 

OPC provides digital signature, and widget packages also provide 
digital signature.  The mechanisms are apparently different.  Should 
they be dropped or unified?

OPC uses %HH for non-ASCII part names.  Meanwhile wiget packaging uses 
a recent version of the ZIP spec, which provides UTF-8 part names.  
Should either OPC or widget packaging be changed?

Cheers,
Makoto
