How do I configure a chain file (for intermediate certs) in the native connector for JBossWeb in JBoss AS 7.1.1?

I found information @ http://docs.jboss.org/jbossweb/7.0.x/apr.html that made it look like you could practically use the settings from apache, but they don't match the XSD. (And don't work.)

I'm sure this is simple - can someone please point me at the correct docs for this?
