Description:
------------
I have a sequenced type defined by a schema with mixed=true.  I can load an instance of this using the XML DAS, write it out again and all is fine.

The problem occurs when I clone the SDO into a new XML_Document and then write that out (can be using the same XML DAS).  All sequence text/formatting is lost as a result.  I have checked and the new SDO is still sequenced, it's just the  sequence content which has been lost.


Reproduce code:
---------------
Test case can be provided on request.

Expected result:
----------------
Cloning should preserve sequence data.

Actual result:
--------------
Cloning loses sequence information.
