   In a similar way you can use antiquotations to refer to theorems or simpsets:
 
   @{ML_response_fake [display] "@{thm allI}" "(\<And>x. ?P x) \<Longrightarrow> \<forall>x. ?P x"}
-  @{ML_response_fake [display] "@{simpset}" "\<dots>"}

-  (FIXME: what does a simpset look like? It seems to be the same problem

+  In the second example, the function @{ML rep_ss in MetaSimplifier} returns a record
