I believe that schema.org is purposely avoiding the strict definition of 
domains and ranges. As it says in the documentation:

"The decision to allow multiple domains and ranges was purely pragmatic. 
While the computational properties of systems with a single domain and 
range are easier to understand, in practice, this forces the creation of 
a lot of artifical types, which are there purely to act as the 
domain/range of some properties. "

If the two (schema.Book and schema.Identifier) are not disjoint, does it 
matter?
