* 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.
