- the element can be reused (so LastName can be used (ref'd) in multiple places)

- the element is defined in one place (so changing the type of
LastName only needs to be done once, not everywhere that it's used)

- the types are exposed to applications, so you can match on type
define variables as that type in schema-aware XSLT or XQuery

- it follows a consistent style, and turns the upper part of your
schema into a data dictionary :)
