I think Andy addressed this, but just in case:

The JDO implementation is responsible for parsing the .jdo, .orm,  
and .jdoquery metadata files. If they use a standard parser, and give  
no performance hints, the parser will try to go to the web and fetch  
the DTD. But a properly implemented JDO will tell the parser to give  
it a chance to resolve URLs of DTDs to locally cached copies of the  
public DTDs.

Once JDO 2 is final, and approved by the JCP, we'll update the public  
Sun web site with the approved versions of the DTD and XSD files. But  
this is just for reference since most JDO implementations won't use
