maintainParty transaction IBM MDM and the symbol '&' in xml

ETL-Informatica team prepares an XML (maintainParty transaction) to be consumed by IBM-MDM .

In general an XML cannot have the symbol '&' and it has to be replaced by &

Instead of repacing the symbol '&' by the entity & , is there any other way that automatically Informatica or MDM can parse the values and make is as proper xml by converting all & into &

The reason I ask is, in production env , ETL team sends with '&' symbol and mdm consumes it properly.

However, in test servers it throws the error below. hence I am trying to understand if there is any configuration in MDM or Informatica where it will convert all & symbol to proper entities.

Request:

If they are using an XML Generator transformation in Informatica to create the XML to MDM it should automatically convert & to &.

Maybe they are overwriting this property? https://kb.informatica.com/solution/14/Pages/109542.aspx
