 If this behaviour is too restrictive for your use case, a possible solution might be to first do a project-specific transformation to re-order/select your desired elements.
 
+For CMIF version 2 compatibility, the `<note>` and the `<ref>` elements in it are passed through by this function. (Currently, the CMIFerator contains no mechanism to create these elements.)
