Cause:
======
Catalog function Instance.updateInstanceFromXML() loads the concept referred to the ExtID in the XML and updates the concept based using the XML string. The exception will be thrown when the loaded concept  does not match the concept type (schema) referred in the XML (different properties).

Resolution:
========
Update your code to  guarantee that the schema is the same for the loaded concept.
