Shouldn't byte range locking be mentioned for the Windows platform? 

For Unix locking, it is mentioned that "different kinds of locks may be applied to different sections (byte ranges) of a file". This is not mentioned for the Windows platform. 

However, when I checkout the LockFile function in msdn, it seems to me that this is also possible on the windows platform, though only for "server" editions of the OS. I'm not a file-locking specialist, so I'm hesitating a bit to edit the article...
