More than this, a schema is a specification and a contract. If you're 
interchanging data with a business partner, or within a business 
community, you need a specification of what data you intend to 
interchange and you need a way of validating that the data conforms to 
the specification. If JSON is to move out of its current niche of being 
used to communicate, in effect, between different parts of the same 
application, then it's almost inevitable it will start to acquire some 
of the baggage that makes XML seem so complicated.
