you are right, they are needed at runtime, too. For example, if the 
schema-mapping is stored in these files, the jdo-implementation obviously 
needs it. Even if no vendor-extensions are present, they have to be present 
to know some settings for persistent fields, for example, whether to store 
embedded or not, whether a field is transient (not to be confused with the 
java keyword with the same name), transactional or persistent, of which 
classes collection members are and so on...
