/**
 * 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.
