I think the authors should provide custom AssertionBuilder s rather than a
custom
AssertionBuilderFactory.

And yes .. we should be able to specify how to locate such custom
AssertionBuilders. For example we are using only Sun service provider
mechanism at the moment. But I think we should also use a System.propertyand
property.properties file to locate any custom AssertionBuilders in the
system.

sounds good !!

How about making the AssertionBuilderFactory a singleton.  Then the
PolicyEngine can get hold of an instance by

AssertionBuilderFactory factory = AssertionBuilderFactory.getInstance();


and a user can add custom AssertionBuilders programmetically by

AssertionBuilderFactory factory = AssertionBuilderFactory.getInstance();
factory.register(...);

Also when AssertionBuilderFactory.getInstance() is called for the first
time  we can
use Sun Service Provider interface, or a system property or a property file
to locate
the initail set of  AssertionBuilders available in the system.

sounds  good !

I will create a Jira and attach the patch. If there would be no

sure .. please do start  a conversation  in the mailing list so that we can
hear what
other has to say also ..
