There are already places in the spec where it provides a "starter set" 
of values for otherwise unconstrained attributes (format=, for example). 
I would expect that pattern to be used for any attribute we unenumerate 
in 1.2.

Note that in XSD schemas you can express this formally by defining a 
type that is a union of a finite enumeration and another lexical type 
that governs values not in the enumeration.

Cheers,
