Oracle Error Message

ORA-19246: validation failed – element string not found in in-scope element declarations

Reason for the Error

The validation mode was strict and the element-constructor contained an element name that was not present in the in-scope element declarations.

Solution

Fix the validation mode to be lax or import the schema definition that contains the required element declaration.
