The test uses the 'rect' element, as well as basic fill (solid primary colors), stroke (black 1-pixel lines), font-family and font-size properties.

The two blue rectangles and the yellow are in the g labeled rects. The blue rectangles inherit a fill color the green rect has a fill specified and it should not be overwritten. The two yellow rectangles should inherit the fill color and the transform attribute, they should be yellow and rotated at -20 degrees. These two rectangles are in g "yellowNrotate", that g is nested inside g "gratuitiousG". The black rectangle in the upper right, has no attributes inherited from its parent. The focus is nesting of g elements and passing on of attributes.
