Some of these API jars are designed to be combined with an implementation
jar and used in that way. Others are not.

Ideally, the API jars would include only the API class files. They definitely
should not contain any other class files, but honestly we haven't worried that
much about resource files. If it was my choice, they wouldn't include them,
but I haven't looked into all the cases to know if that would be a problem.
We've considered putting related schema files in the API jar files, but since
the specs don't define that the schema files are available as resource files
in your classpath, we haven't done that.

At this point it seems more like a bug to me than "by design".
