It would help me if you explained the diffs and the *reasons* for the proposed changes. E.g, the new text says: This term means that the feature or behavior is a limited requirement of the specification, so that an implementation has a conditional obligation to implement the feature or to behave as defined, unless there is a strong, explicitly described reason not to do so in particular circumstances. Those who implement the specification or deploy conformant technologies need to understand and carefully weigh the full implications of violating the requirement before doing so. The term "RECOMMENDED" is equivalent to "SHOULD". The wording "unless there is a strong explicitly described reason not to do so in particular circumstances" is new wording and my first reaction is it's not helpful. I.e., "explicitely described by who?" Explicitely specified in the text? If so, that seems unworkable in practice. What problem is this bis document intended to fix?
