+ * Occasionally, a certain attribute will need to be removed and popped onto

+ * another value.  Instead of creating a complex return syntax for

+ * HTMLPurifier_AttrDef, we just pass the whole attribute array to a

+ * specialized object and have that do the special work.  That is the

+ * family of HTMLPurifier_AttrTransform.

+ *

+ * An attribute transformation can be assigned to run before or after

+ * HTMLPurifier_AttrDef validation.  See HTMLPurifier_HTMLDefinition for

+ * more details.
