+Internally, definition of meshing parameters to apply for
+discretization of a certain sub-shape, for example an edge of a
+compound of solids, starts from searching an algorithm, 1D as for the
+edge. The following sub-shapes are sequentially checked for presence
+of a sub-mesh where 1D algorithm is assigned:
+<ul>
+<li> the \b edge itself</li>
+<li> <b>groups of edges</b> containing the edge, if any</li>
+<li> \b wires sharing the edge</li>
+<li> \b faces sharing the edge</li>
+<li> <b>groups of faces</b> sharing the edge, if any</li>
+<li> \b shells sharing the edge</li>
+<li> \b solids sharing the edge</li>
+<li> <b>groups of solids</b> sharing the edge, if any</li>
+<li> the <b>main shape</b></li>
