++ This test checks for recursion in 'use' elements. The passing conditions are that the browser does not crash, and that at least one orange circle, and one yellow circle, and a line of green text are rendered.
++ Also, on an implementation-specific basis, additional orange and yellow circles with a dashed gray stroke may or may not be rendered, depending upon when and how the implementation detects the circular reference,
++ with the number of dashed circles of a given color indicating now many times the level of recurrsion permitted by the implementation.
