"The patented XY system enables you to position the shelves along vertical Y-axis and the pairs of load-bearing profiles along horizontal X-axis. Positioning along X and Y is completely free, without any preset positions. This creates a load-bearing framework that can be completed with backs, sides, tilting or leaf doors, drawer units and a range of other accessories."^^<http://www.w3.org/2001/XMLSchema#string>
