No: physical points are exactly like other physicals (line, surface
volume), they group elementary geometrical entities (in this case,
geometry points).

What you probably want is to associate a boundary condition with the
nodes located on some (group of) geometrical entities. So 1) save that
group as a physical group 2) loop over the elements in that group and
apply the condition on the nodes of these elements.
