This document looks good on an initial quick read -- with one possible exception. It says:
Atom processors that do recognize the parameter SHOULD detect and report inconsistencies between the parameter's value and the actual type of the document's root element.
This would seem to be creating a directive concerning behavior which is not directly related to interoperation between systems. (I'm assuming that the destination of the "reports" is the user of the application, a log file, or something like that.) Thus, it seems to me that it might be inappropriate to use the SHOULD word since IETF apps are supposed to be focused on interoperation and are supposed to avoid constraining application behavior unnecessarily. May I suggest that you rewrite this sentence in a manner similar to that below: "It is strongly recommended that Atom processors that do recognize the parameter detect and report ...." bob wyman
