<LI>If there are no boundary elements (i.e., if the local part of
the connectivity graph is self-contained) the output vector is set
to the ``not allocated'' state.

<LI>Otherwise the size of <code>bndel</code> will be exactly equal to the
number of boundary elements.
<LI>This routine returns a <code>.true.</code> value for an index
that is local to the current process, including the halo
indices
