An instance of this XML document may contain mappings for an arbitrary 
number of classes. The class mappings may contain associations to classes
mapped in the same document or in another document. No class may be 
mapped more than once. Each document may also contain definitions of an
arbitrary number of queries, and import declarations of arbitrary classes.
