Fig. B.7 depicts the syntax of the BOUNDARIES section. The
definition is very similar to that of the ATTRIBUTES section. The differences are
that (a) in the boundary grid element definition the number of point references
is one less than with the attributes and (b) a boundary definition may consist
of only the reference to a grid. To avoid ambiguities with the definition of the
ATTRIBUTES section the respective rules are prefixed with a "B".
