-\item [$\isarkeyword{axclass}~c < \vec c~axms$] defines an axiomatic type
-  class as the intersection of existing classes, with additional axioms
-  holding.  Class axioms may not contain more than one type variable.  The
-  class axioms (with implicit sort constraints added) are bound to the given
-  names.  Furthermore a class introduction rule is generated, which is
-  employed by method $intro_classes$ to support instantiation proofs of this
-  class.

-\item [$\isarkeyword{instance}~c@1 < c@2$ and $\isarkeyword{instance}~t ::
-  (\vec s)c$] setup a goal stating a class relation or type arity.  The proof
-  would usually proceed by $intro_classes$, and then establish the
-  characteristic theorems of the type classes involved.  After finishing the
-  proof, the theory will be augmented by a type signature declaration
-  corresponding to the resulting theorem.
