Migration from 2 to 3 for RelationshipErrorHandlerFactory?

You state in the changelog from version 2 to 3

"Removed OpenXmlSettings.RelationshipErrorHandlerFactory and associated types and replaced with a built-in mechanism to enable this"

I cannot find any documentation on how to handle this when migrating. Can you point us in the right direction please? Specifically trying to rewrite a RelationshipErrorHandler.

Start with the version 2-to-3 changelog entry about removing OpenXmlSettings.RelationshipErrorHandlerFactory and its associated types. Trace the documented replacement and the RelationshipErrorHandler migration path, then identify where migration guidance should be added. Done means users can understand how to handle relationship errors in version 3.
