title: when should I use BOM to XOM mapping ExtenderName in ILOG Jrules
body: <p>In the rule studio BOM editor , there is BOM to XOM mapping window and it asks for execution name and extender name. I can write java code in a separate project and import it as BOM. So what is the purpose of this extender mechanism ? As always IBM doc says how to do it. But doesn't tell why !</p>
