 In general, \isacommand{recdef} supports termination proofs based on
 arbitrary well-founded relations as introduced in \S\ref{sec:Well-founded}.
 This is called \textbf{well-founded

+is total iff the set of all pairs $(r,l)$, where $l$ is the argument on the
 left-hand side of an equation and $r$ the argument of some recursive call on
 the corresponding right-hand side, induces a well-founded relation.  For a
 systematic account of termination proofs via well-founded relations see, for
