If you're using the XMLTYPE constructor to insert your XML into the DB you can avoid the well-formed validation declaring that the xml is well formed:
SQL> insert into MYXMLTABLE values (
  2  XMLTYPE('
  3  <ROOT a="1" a="3"/>
  4  ',null,0,1));
1 row created.Oracle inserts the xml in the table but, obvoiusly, you'll never be able to use it as an XML file:
SQL> select object_value
  2  from MYXMLTABLE ;
OBJECT_VALUE
<ROOT a="1" a="3"/>
SQL> select extract(object_value,'/*')
  2  from MYXMLTABLE ;
ERROR:
ORA-31011: XML parsing failed
ORA-19202: Error occurred in XML processing
LPX-00224: multiple occurrences of attribute "a" found
Error at line 8Max
