The javadocs:

https://hudson.jboss.org/hudson/job/drools/lastSuccessfulBuild/artifact/trunk/target/javadocs/stable/drools-api/org/drools/ChangeSet.html

There are a number of unit tests you can follow:

The properties file does not offer enough flexibilility to support all 
resource types - the xml really is quite simple - how do you specify the 
worksheet name for a decision tree? In some ways it's actually simpler 
and more powerful, as there is no separate line for directories, it's 
just another resource and it detects that it's a directory. ChangeSets 
will eventually support remove and modify, for incremental knowledgebase 
changes, so the properties file just doesn't cut it.

<change-set>
   <add>
      <resource source='http://www.domain.com/test.drl' type='DRL' />
      <resource source='file://data/somedir' type='DRL' />
      <resource source='http://www.domain.com/test.xls' type='DTABLE' >
         <decisiontable-conf worksheet-name='sheet10' input-type='XLS' />
      </resource>
  </add>        
</change-set>
