Apple binary plist and/or keyed archive file format documentation?

Are Apple's binary plist format and/or the related keyed archive fo开发者_JAVA技巧rmat actually documented anywhere?

I know that there is Apple open source code for binary plist parsing out there, which is a good start, but reverse-engineering the format and its revisions from that is less than ideal. Is there any actual explicit documentation on this format?

Thanks.

I don't think so. They're formats private to Apple. As jackrabbit commented above, you should convert it to an XML plist and use any of the XML parsers available if you want interoperability.
