Update regarding DR 09-0157

[MURATA Makoto (FAMILY Given)]

I believe that the problems comes from W3C XML Schema. 

I tried to change xsd:sequence by xsd:all for EG_RPrBase (not EG_RPrContent!). 
Then, Xerces-J returns an error already.

Should we just reopen this DR and eliminate the change from the DCOR?

BTW, this is a problem of W3C XML Schema.  RNG does not have this
problem.
