Section 6.7.11.13:

    	The facets pattern is designed to be used as a normal. Like bumps or
    	wrinkles, it is not suitable for use as a pigment: it will cause an
    	error.

The wrinkles pattern works--in B7 at least--as a pigment.

Section 3.7.5:

    	It is important to remember that as of POV-Ray 3, all patterns that
    	work with pigments work as normals as well (and vice versa, of
    	course)

The facets pattern works in normals but not in pigments.  I assume this is 
a problem with the documentation rather than a bug in the code.
