+      <C>DotHighlightedDigraph</C> produces a graphical represenation of the
+      digraph <A>digraph</A>, where the vertices in the list <A>verts</A>, and
+      edges between them, are drawn with colour <A>colour1</A> and all other
+      vertices and edges in <A>digraph</A> are drawn with colour <A>colour2</A>.
+      If <A>colour1</A> and <A>colour2</A> are not given then
+      <C>DotHighlightedDigraph</C> uses black and grey respectively. <P/>
+
+      Note that <C>DotHighlightedDigraph</C> does not validate the colours
+      <A>colour1</A> and <A>colour2</A> - consult the GraphViz documentation to
+      see what is available.
+
+      See <Ref Attr="DotDigraph"/> for more details on the output.<P/>
