This is where the concept of an "application profile" would fit in -- 
schema's definitions are loose, allowing a variety of interpretations. 
For a particular application, however, one could set constraints that 
are stricter than those defined in schema. It appears to me from the 
conversations on that list that some users of schema are already setting 
up their own constraint rules within closed systems.

I'm not entirely convinced that schema is a "special candidate" for 
validation; no more so than other general-purpose vocabularies like DC 
terms. But it could indeed be a useful test case because it is widely 
used already.
