Recently I saw this definition of "model":

	The difference between a model and
 	an instance is that a model represents
 	a set of instances.

Under that definition, it seems reasonable to call an XML Schema a "data model" since one XML Schema is created and it represents a set of XML instances.

Do you agree?
