166 |  | <div class="iffy-element-desc">
167 |  | <p><strong>When a subelement of <code>item</code></strong></p>
168 |  | <p>Represents a <em>hint</em> to RSS consumers that "push" — announce, rebroadcast, or notify — items whether this item should be so pushed. Consumers are free to ignore this hint or make use of it as they wish.</p>
169 |  | <p>MUST contain an <a href="#iffy-policy"><code>iffy:policy</code></a> element, whose values MUST BE one of</p>
170 |  | <ul>
171 |  | <li><code>Always</code> — the item should always be notified</li>
172 |  | <li><code>Never</code> — the item should never be notified</li>
173 |  | <li><code>Piggyback</code> — the item should be notified as part of digests or other announcements of multiple items, but should not constitute its own announcement.</li>
174 |  | </ul>
175 |  | <p>MAY contain an <a href="#iffy-restriction"><code>iffy:restriction</code></a> element, which represents an application-specific restriction over the consumers to which it is addressed. No restrictions are placed on the content of the <code>iffy:restriction</code> element. Applications can define restrictions as they see fit.</p>
176 |  | <p>An <code>iffy:hint-announce</code> element with NO <code>iffy:restriction</code> or an empty <code>iffy:restriction</code> tag should be interpreted as the intended default for ALL applications not addressed by an <code>iffy:hint-announce</code> with a more specific restriction.</p>
177 |  | <p>Multiple <code>iffy:hint-announce</code> elements may be placed within a single <code>item</code>, provided that only one has an omitted or empty <code>iffy:restriction</code>, and all <code>iffy:hint-announce</code> elements containing an <code>iffy:restriction</code> contain a unique restriction. Each <code>iffy:restriction</code> SHOULD apply to nonoverlapping application-specific contexts. If that is not the case, how applications prioritize or respond to conflicting <code>iffy-hint-announce</code> elements whose restrictions both apply must be determined by the application.</p>
