+[NOTE]
+====
+If you declare a rule unit in DRL, the rule unit class will be generated by
{PRODUCT} at build time. It means that you can't refer to the class in your
client codes. Declared rule units are only useful when the client is also
auto-generated, for example, REST endpoint generation by Drools-Quarkus
integration.
+====
+
To separate the fact types from the rule unit for use with other DRL rules,
you can declare the types in a separate DRL file and then use the DRL rule file
to declare the data sources by using the `RuleUnitData` interface
implementation:
