Hi, This means to use the definitions provided by me in C802.20-03/67: "MUST" or "SHALL" These words or the adjective "REQUIRED" means that the item is an absolute requirement. "MUST NOT" This phrase means that the item is an absolute prohibition. "SHOULD" This word or the adjective "RECOMMENDED" means that there may exist valid reasons in particular circumstances to ignore this item, but the full implications should be understood and the case carefully weighed before choosing a different course. "SHOULD NOT" This phrase means that there may exist valid reasons in particular circumstances when the listed behavior is acceptable or even useful, but the full implications should be understood and the case carefully weighed before implementing any behavior described with this label. "MAY" This word or the adjective "OPTIONAL" means that this item is truly optional. One implementation may include the item because the target marketplace requires it or because it enhances the product, for example; another implementation may omit the same item.

I support use of the IEEE style manual across the board. I believe that Bob Love provided a good explanation of how "will" should (shall?) be used based on the IEEE style manual. His comment was as follows: -----Original Message----- From: owner-stds-80220-requirements@majordomo.ieee.org <mailto:owner-stds-80220-requirements@majordomo.ieee.org> [mailto:owner-stds-80220-requirements@majordomo.ieee.org]On Behalf Of Robert Love Sent: Wednesday, July 23, 2003 10:09 AM To: stds-80220-requirements@ieee.org <mailto:stds-80220-requirements@ieee.orgSubject> Subject: RE: stds-80220-requirements: Shall-Will-Should in 802.20 Requirements v5 - C802.20-03-6921 I am in general agreement with Joseph's recommendations for the use of "shall" and "should" which closely follow the style guide. I would advise that we attempt to limit the use of "will" for explanations that describe conditions that naturally follow from set conditions so there is no confusion over the possibility that we must be able to conformance test for the condition. An example of "will" being used according to this guideline is: "Loss of signal will result in dropped packets." Best regards. Robert D.

The only question remaining is if we need a definition of "will" as proposed by Joanne.

The use of the word must is deprecated and shall not be used when stating mandatory requirements; must is used only to describe unavoidable situations. The use of the word will is deprecated and shall not be used when stating mandatory requirements; will is only used in statements of fact. The word should is used to indicate that among several possibilities one is recommended as particularly suitable, without mentioning or excluding others; or that a certain course of action is preferred but not necessarily required; or that (in the negative form) a certain course of action is deprecated but not prohibited (should equals is recommended that). The word may is used to indicate a course of action permissible within the limits of the standard (may equals is permitted). The word can is used for statements of possibility and capability, whether material, physical, or causal (can equals is able to)."

"shall" expresses a provision that is binding 2. "should" and "may" expresses non-mandatory provisions 3. "will" expresses a declaration of purpose. It may be necessary to use "will" in cases where the simple future tense is required Joseph Cleveland Director, Systems & Standards Wireless Systems Lab Samsung Telecommunications America Richardson, TX 75081 (O) 972-761-7981 (M) 214-336-8446 (F) 972-761-7909 This mail passed through mail.alvarion.com ************************************************************************ ************ This footnote confirms that this email message has been scanned by PineApp Mail-SeCure for the presence of malicious code, vandals & computer viruses. ************************************************************************ ************ This mail was sent via mail.alvarion.com ************************************************************************ ************ This footnote confirms that this email message has been scanned by PineApp Mail-SeCure for the presence of malicious code, vandals & computer viruses. ************************************************************************ ************ This mail passed through mail.alvarion.com ************************************************************************ ************ This footnote confirms that this email message has been scanned by PineApp Mail-SeCure for the presence of malicious code, vandals & computer viruses. ************************************************************************ ************ This mail was sent via mail.alvarion.com ************************************************************************************ This footnote confirms that this email message has been scanned by PineApp Mail-SeCure for the presence of malicious code, vandals & computer viruses. ************************************************************************************
