XML format configuration file

Allow BTM configuration to be done with an XML file format , this would have some advantages over properties file format:

• More readable (IMHO)
• XSD constrained (less error prone)

A workaround could be to use Spring configuration, but this can't be achieved when you are running BTM with Tomcat/Jetty lifecycle bindings.

Log4J can do it (both XML and Properties file format) why not BTM?
