-/**
- * 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.
