-IPF 5.0 comes with some changes that should be considered when upgrading from earlier IPF versions
+IPF 5.0 comes with some changes that should be considered when upgrading from earlier IPF versions.
 
-## Renamed Classes and Modules 
+## Changes in ATNA audit dataset enrichment 
 
-* Interface `org.openehealth.ipf.commons.ihe.ws.cxf.audit.XuaProcessor` was renamed to
-  `org.openehealth.ipf.commons.ihe.ws.cxf.audit.WsAuditDatasetEnricher`, because this
-  mechanism can be used for all types of Web Service audit dataset enrichment and not 
-  only for extracting data from XUA tokens.
+Older IPF versions contained the module `ipf-commons-ihe-xua` which provided routines to propagate 
+particular elements of XUA authorization assertions into ATNA audit datasets.  In IPF 5.0, this 
+module is not present anymore.  Instead, a concept of a "Web Service audit dataset enricher" 
+is introduced.  
 
-* Module `ipf-commons-ihe-xua` (containing an implementation of the aforementioned interface) 
-  was renamed to `ipf-commons-ihe-swissepr`, because its functionalities relate not only
-  to extracting data from XUA tokens and are specific for the Swiss EPR.
+IPF provides two enricher implementations out of the box:
+* `org.openehealth.ipf.commons.ihe.ws.cxf.audit.XuaWsAuditDatasetEnricher` — fulfills requirements 
+   of the IHE [XUA](https://profiles.ihe.net/ITI/TF/Volume2/ITI-40.html) profile.
+* `org.openehealth.ipf.commons.ihe.ws.cxf.audit.SwissEprWsAuditDatasetEnricher` — fulfills both IHE XUA 
+  requirements and the requirements of the 
+  [Swiss Electronic Patient Record](https://www.e-health-suisse.ch/en/technique/technical-interoperability/specifications-for-the-epr-implementation).
 
+A Web Service audit dataset enricher can be configured in an Audit Context
+by providing a Spring bean of the type `org.openehealth.ipf.commons.ihe.ws.cxf.audit.WsAuditDatasetEnricher`,
+or by specifying an enricher's class name in the corresponding Spring Boot configuration property.
+
+Example for Spring context XML configuration:
+```xml
+<bean id="auditContext" class="org.openehealth.ipf.commons.audit.DefaultAuditContext">
+    <property name="auditEnabled" value="true"/>
+    <property name="auditMessageQueue" ref="myMessageQueue"/>
+    <property name="auditSourceId" value="ipfapp"/>
+    <property name="wsAuditDatasetEnricher">
+        <bean class="org.openehealth.ipf.commons.ihe.ws.cxf.audit.SwissEprWsAuditDatasetEnricher"/>
+    </property>
+</bean>
+```
+
+Example for Spring Boot YAML configuration:
+```YAML
+ipf:
+  atna:
+    audit-enabled: true
+    audit-queue-class: my.project.atna.DevNullMessageQueue
+    audit-source-id: ipfapp
+    ws-audit-dataset-enricher-class: org.openehealth.ipf.commons.ihe.ws.cxf.audit.SwissEprWsAuditDatasetEnricher
+```
