Hi, As of today we are using Drools 2.0, where we are converting the xml in to java objects before validating by drools engine. Can we send xml directly to Drools 5.2 or higher and validate directly instead of conversion from xml to java. Also, please share if there are any design considerations while migrating from drools 2.0 to 5.2 or higher. Which version is stable and all.
