This issue is common to EPUB, OOXML, and ODF (even ODF 1.2).  I would
like to have the same solution for all of them, which is to allow 
more than one dc:creator element (for example) having diffent values 
for @xml:lang.

Some changes in our CORs theoretically destroy some implementations. 
Let alone AMDs.  In this case, will some real implementations really
have troubles?   If not, I would like to use the simplest solution
common to all relevant specifications.
