 After running the workflow you will find the generated Langium output in `./langium` folder.

+##### Fragment options
+
+
+- `outputPath` - Target output folder
+- `prefixEnumLiterals` - If `true`, enum literal types will be prefixed with the enum type name to avoid name conflicts with other enum literals. Default is `true`. Example: `enum Color: RED;` will create: `Color returns Color: Color_RED; Color_RED returns string: 'RED';`
+- `useStringAsEnumRuleType` - If `true`, Enum types will be handled as strings. Only relevant for generated metamodels. Default is `false`.
+- `generateEcoreTypes` - If `true`, types from the Ecore metamodel will also be generated. If `false`, ecore data types will be replaced with Langium data types. Types that are not convertible to Langium built in types will be generated as string. Default is `false`.
+- `removeOverridenRules` - In case a rule from the imported grammar was overwritten, Langium will report a duplicate error. If `true`, the super grammar rules will be skipped in favour of the current grammar rules. Default is `false`.
