Tim, as far as I know, feature type traversal depends entirely on the support of the DataAccess to which the Query is submitted. The application schema (app-schema) DataAccess supports this type of traversal. For example, if you have a nested (chained) feature type that is a property of a top-level feature type, you can filter the top-level feature type based on the properties of the nested type.
Kind regards, Ben.
