Also, I can see here -- ORA-19279: XPTY0004 - XQuery dynamic type mismatch: expected singleton sequence - got multi-item sequence
that you have used another technique XMLNamespaces() for the same.
select x.*
from abc t
   , xmltable(
       xmlnamespaces(
         default 'urn:swift:xsd:fin.970.2011'
       , 'urn:swift:xsd:mtmsg.2011' as "ns0"
     , '/ns0:FinMessage/ns0:Block4/Document/MT970/F61a/F61'
       passing t.col1
       columns F61ValueDate                Varchar(40) Path 'ValueDate'
             , DebitCreditMark             Varchar(40) Path 'DebitCreditMark'
             , Amount                      Varchar(40) Path 'Amount'
             , TransactionType             Varchar(40) Path 'TransactionType'
             , IdentificationCode          Varchar(40) Path 'IdentificationCode'                 
             , ReferenceForTheAccountOwner Varchar(40) Path 'ReferenceForTheAccountOwner'
             , SupplementaryDetails        Varchar(40) Path 'SupplementaryDetails'       
     ) x;
What you are trying to do here? and why that "default" namespace?
Also, I'll also go through the docs in this meantime.
