/**
 * Processes an entire attribute array for corrections needing multiple values.

 * 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.
