* Allows multiple validators to attempt to validate attribute.

* Composite is just what it sounds like: a composite of many validators.
* This means that multiple HTMLPurifier_AttrDef objects will have a whack
* at the string. If one of them passes, that's what is returned. This is
* especially useful for CSS values, which often are a choice between
* an enumerated set of predefined values or a flexible data type.
