Steven Hawkins resolved TEIID-2975.
-----------------------------------

    Resolution: Done


Added a narrow fix that affects incoming sqlxml values from translators that need to be saved to disk.  It is possible that we may want to expand this fix in the future to all xmloutputfacties we use depending upon whether udfs or other places in code may be returning child nodes with inherited namespaces.  However that will change quite a few expected results as it will add in at least the default namespace declaration, so that was not done yet.
