I don't know about any spec. The bug on Sun site [1] seems to prove there is no spec for the binary format of DTD. In this implementation binary format is just a serialized version of DTD based on HTML 4.01 Transitional. Why do we need to read the binary DTD of Sun? Harmony classlib will have its own bdtd, which it is able to deal with. IMHO if we need to, we can create our own html32.bdtd.
