  * Type names have form `package.type` or just `package` if referring to the package export
  * object. If `package` contains a `.` character it must be enclosed in single quotes, such as `'package'.type`.
+ *
+ * A type name of form `(package)` may also be used when refering to the package export object.
+ * We allow this syntax as an alternative to the above, so models generated based on `EndpointNaming` look more consistent.
