This is maybe cumbersome, but you can identify DG elements by checking
the number of dofs per mesh entity through ufc::dof_map, with the function
/// Return the number of dofs associated with each cell entity of
dimension d
virtual unsigned int num_entity_dofs(unsigned int d) const = 0;
if
dm->num_entity_dofs(0) == dm->max_local_dimension()
then no dofs are shared between elements.
However this does not cover elements where dofs are shared but
the functions are still discontinuous in certain senses.
I guess more information will be needed in the ufc element classes.
