Portions of this section conform to \rfc{2119}: ``Key words for use in RFCs to
|
|
Indicate Requirement Levels''. Certain terms from the RFC have been expressly
|
|
avoided; for example, the terms ``should'' and ``should not'' are not used
|
|
because this specification's audience has the capability to alter the
|
|
specification to resolve implementation issues and should exercise that ability.
|
|
|
|
\begin{description}
|
|
\sigauth{NL}
|
|
\dt{conforming implementation}

|
An implementation that meets all of the requirements of this specification.
|
|
|
|
\sigauth{NL}
|
|
\dt{Deprecated}
|
|
When used within context of this specification: the feature or requirement
|
|
will be removed in future revisions of this specification.
|
|
|
|
\sigauth{NL}
|
|
\dt{Exempt}
|
|
Denotes a condition under which an implementation need not conform to a
|
|
requirement.
|
|
|
|
\sigauth{NL}
|
|
\dt{implementation}
|
|
Software that implements this specification.
|
|
|
|
\sigauth{NL}
|
|
\dt{May; Optional}
|
|
Alternatively, the adverb ``optionally''; denotes a requirement whose
|
|
implementation is not required and may be omitted; such \shall be used only to
|
|
provide flexibility for implementors to exercise their best judgment or to
|
|
denote requirements that are not essential to the operation of the
|
|
implementation.
|
|
|
|
\sigauth{NL}
|
|
\dt{Removed}
|
|
A feature or requirement mentioned in an earlier revision of this
|
|
specification has been removed and will not be superseded.
|
|
|
|
\sigauth{NL}
|
|
\dt{section}
|
|
The section containing the mention of this term, as well as any subsections
|
|
contained within it.
|
|
|
|
\sigauth{NL}
|
|
\dt{Shall; Must}
|
|
Denotes a mandatory requirement. If an implementation does not implement such
|
|
a requirement, then the implementation is not conforming and the results under
|
|
such a requirement are \undefined.
|
|
|
|
\sigauth{NL}
|
|
\dt{Shall Not; Must Not}
|
|
Denotes an absolute prohibition. If an implementation does not honor such a
|
|
prohibition, then the implementation is not conforming and the results under
|
|
such a requirement are \undefined.
|
|
|
|
\sigauth{NL}
|
|
\dt{Superseded}
|
|
The feature or requirement mentioned in an earlier revision of this
|
|
specification has been removed and replaced by another.
|
|
|
|
\sigauth{NL}
|
|
\dt{Undefined}
|
|
The error condition results in behavior that is not defined by a particular
|
|
standard; this term \shall be used only to document other standards or
|
|
specifications---it \shall not be used to introduce undefined behavior into
|
|
this specification.
|
|
|
|
\sigauth{NL}
|
|
\dt{Unspecified}
|
|
The behavior is not determined by this specification or is inconsequential to
|
|
the implementation's operation.
