from current version:

>>> If an error occurs, the server SHOULD set the appropriate error code in the error field of an error chunk. However, if the error does not involve invalid usage (such as a request beyond the bounds of the file), a server MAY reply with a single block status descriptor with /length/ matching the requested length, and /status/ of 0 rather than reporting the error.

- single block status descriptor for each context? Isn't it implementation defined? Or we finally decided to force 0 status to be safe default for all contexts? If it is so, it would be better to describe this separately. However, personally, I'd prefer to not define contexts internal semantics at all.
