<remarks>
<p>Implemented requirements within a component or capability in a component definition provide a means to suggest possible control implementation details, which may be used by a different party when authoring a system security plan. Thus, these requirements defined in a component definition are only a suggestion of how to implement, which may be adopted wholesale, changed, or ignored by a person defining an information system implementation.</p>

<p>Use of <code>set-parameter</code> in this context, sets the parameter for the control referenced in the containing <code>implemented-requirement</code> applied to the referenced component. If the <code>by-component</code> is used as a child of a <code>statement</code>, then the parameter value also applies only in the context of the referenced statement. If the same parameter is also set in the <code>control-implementation</code> or a specific <code>implemented-requirement</code>, then this <code>by-component/set-parameter</code> value will override the other value(s) in the context of the referenced component, control, and statement (if parent).</p>
