In Cúram V5.2, CER allowed you to split your rule set into smaller files which may aid the concurrent development of rule sets among several documents.
See Include Statement for details on how to split up your rule set.
Prior to loading your CER rule set onto the data, it will be automatically "consolidated" into a single rule set file by the application's build scripts (specifically, the build creole.consolidate.rulesets target).
All other types of Include statement are intentionally left unchanged in the consolidated output.
