The current version is very confusing: > 1.4 Additional feature: Delegate lookup > This section describes an additional feature that *MAY* be added to a > container. > … > Implementation of this feature is therefore *RECOMMENDED*.
>From RFC 2119 <https://tools.ietf.org/html/rfc2119>: > 3. *SHOULD* This word, or the adjective "*RECOMMENDED*", mean that there > may exist valid reasons in particular circumstances to ignore a > particular item, but the full implications must be understood and > carefully weighed before choosing a different course. > … > 5. *MAY* This word, or the adjective "*OPTIONAL*", mean that an item is > truly optional. One vendor may choose to include the item because a > particular marketplace requires it or because the vendor feels that > it enhances the product while another vendor may omit the same item. > An implementation which does not include a particular option MUST be > prepared to interoperate with another implementation which does > include the option, though perhaps with reduced functionality. In the > same vein an implementation which does include a particular option > MUST be prepared to interoperate with another implementation which > does not include the option (except, of course, for the feature the > option provides.) Thus, as an implementer, *MAY* or *SHOULD* I implement the delegate lookup feature?
