Action item on additional example for Foreign Part in MCE Best Practices document.

Francis,

Thank you very much!

A specialized media type for ONIX would make sense if there is some special 
processing (such as ONIX fragment identifiers). 

So far, in OOXML,  URIs for namespace names and those for relationship 
types are different.  But I do not see strong reasons for separating them.  
Namespace names should be changed only for intentionally destroy existing 
application programs for new data.  When should we change relationship 
names?  Probably,when we would like to prohibit existing OOXML 
applications from accessing new parts.  Then, it might be a good idea 
to use the same URI.

I don't think that namespace names or relationship types have to be 
resolved.  They are just names.  Thus, I don't think that performance 
is an issue.

Regards,
Makoto
