Per the IEEE Style Manual [B1], 1 this standard includes normative and informative information. Normative text may describe mandatory or optional features. A mandatory feature may have optional as well as mandatory components. For example, a mandatory message may have optional fields. An optional feature may have components that are mandatory if the feature is supported. For example, an optional message might require a certain field. Additionally, a feature may be conditional on support of another feature. For example, if A is supported, at least one of B or C must be supported. In this standard, features are designated as mandatory, optional, or conditional in the introduction to the subclause specifying the feature.
The designation applies to the requirements found in the subclause itself as well as any subordinate subclauses, unless otherwise indicated. The word shall, when applied to a component of an optional feature, indicates that the component is mandatory if the feature is supported, i.e., conditional on support for the  eature. The protocol implementation conformance statement (PICS) in Annex G tabulatessummarizes the  equirements of this standardand their components.
A summary of the minimum supported features necessary for compliance to this standard is provided in 4.1.
1.4 Document conventions
Unless otherwise noted, conventions follow those in IEEE Std 802.11™, including conventions for the ordering of information within data items.
Numbers are decimal unless otherwise noted. Numbers preceded by 0x indicate hexadecimal numbers, so that 0xFF is equivalent to “FF hexadecimal.” Field lengths are in octets unless otherwise noted.
Words in italics refer to data items that appear in the management information base (MIB),primitives, or over the air frames.
Descriptive, informative information is generally found at the beginning of a clause or subclause,with normative text following. Figures are used for illustration and are informative, unless otherwise noted.
Unless otherwise noted, references to a MIB refer to the MLME MIB specified in Annex F.
