STIG Tomcat Application Server 9

We are running WHD 12.7.10 HF1.

While STIGGING using the Tomcat Application Server 9, there are multiple items that refer to the ErrorReportValve and AccessLogValve Valve classNames in the WHD/bin/tomcat/conf/server.xml file.  Does anyone know if we can add these items without breaking WHD or if there's a different place to put the settings that would satisfy the STIGS?   Some examples are: TCAT-AS-000270, TCAT-AS-000050, TCAT-AS-000180, TCAT-AS-001080
