     * Asserts that a transformation happens
     * 
     * This assertion performs several tests on the transform:
     * 
     * -# Transforms a start tag with only $name and no attributes
     * -# Transforms a start tag with $name and $attributes
     * -# Transform an end tag
     * -# Transform an empty tag with only $name and no attributes
     * -# Transform an empty tag with $name and $attributes
     * 
     * In its current form, it assumes that start and empty tags would be
     * treated the same, and is really ensuring that the tag transform doesn't
     * do anything wonky to the tag type.
     * 
     * @param $transformer      HTMLPurifier_TagTransform class to test
     * @param $name             Name of the original tag
     * @param $attributes       Attributes of the original tag
     * @param $expect_name      Name of output tag
     * @param $expect_attributes Attributes of output tag when $attributes 
     *                          is included.

     *                          are omitted.
