331 |  | <div class="iffy-element-desc">
332 |  | <p>Represents a reference to an RSS <code>item</code> in RSS data available elsewhere.</p>
333 |  | <p><code>iffy:item-ref</code> SHOULD be an empty XML element, given meaning by its attributes.</p>
334 |  | <ul>
335 |  | <li>
336 |  | <p>An <code>iffy:item-ref</code> MUST contain an <code>href</code> attribute, which points to a source of RSS data or to an HTML document that refers to RSS data in an HTML <code>link</code> element.</p></li>
337 |  | <li>
338 |  | <p>An <code>iffy:item-ref</code> SHOULD contain a <code>type</code> attribute. The type should either be <code>text/html</code> or <code>application/*rss+xml</code> where the <code>*</code> may refer to the empty string (so just <code>application/rss+xml</code>) or a prefix, <a href="../../2024/11/12/supporting-single-item-rss/index.html">like</a> <code>application/x-single-item-rss+xml</code>. (If a type attribute is missing, a consumer MAY try to examine the contents at <code>href</code> and do the right thing.) (Mime types can, as always, include a parameter, like <code>text/html;charset=UTF-8</code>.)</p></li>
339 |  | <li>
340 |  | <p>An <code>iffy:item-ref</code> MUST contain a <code>guid</code> attribute UNLESS the <code>href</code> refers to <a href="../../2024/11/12/supporting-single-item-rss/index.html">single-item RSS</a>.</p></li>
341 |  | </ul>
342 |  | <p>To resolve an <code>iffy:item-ref</code> consumers should:</p>
343 |  | <ol>
344 |  | <li>
345 |  | <p>Check the <code>type</code> attribute, or if missing, check the contents referred to by the <code>href</code>, to see whether the referent is an HTML or an RSS document.</p></li>
346 |  | <li>
347 |  | <p>If the referent is an RSS document and the <code>iffy:item-ref</code> includes a <code>guid</code> attribute, the <code>item-ref</code> refers to the RSS <code>item</code> element containing a <code>guid</code> element whose contents matched the <code>iffy:item-ref</code>'s <code>guid</code> attribute.</p></li>
348 |  | <li>
349 |  | <p>If the referent is an RSS document and the <code>iffy:item-ref</code> does NOT include a <code>guid</code> attribute, then the <code>item-ref</code> refers to the single RSS item in the document. If there is more than one RSS <code>item</code>, the resolution fails.</p></li>
350 |  | <li>
351 |  | <p>If the referent is an HTML document and the <code>iffy:item-ref</code> contains a <code>guid</code> attribute, the consumer must gather all HTML <code>link</code> elements with <code>rel="alternative"</code> and <code>type="application/*rss+xml</code> where the <code>*</code> may refer to the empty string (so just <code>application/rss+xml</code>) or a prefix, <a href="../../2024/11/12/supporting-single-item-rss/index.html">like</a> <code>application/x-single-item-rss+xml</code>. The type may also contain a parameter, like <code>application/x-single-item-rss+xml;completeness=Content</code> The consumer tries <code>link</code> elements whose <code>type</code> attribute is an exact match to the <code>iffy:item-ref</code>'s <code>type</code> attribute first, in the order they appear in the HTML file, and then other <code>link</code> elements with <code>type="application/*rss+xml</code>, in the order they appear. For each <code>link</code> tried, if the linked RSS contains that an RSS <code>item</code> with the <code>item-ref</code>'s specified <code>guid</code>, then the <code>item-ref</code> refers to that <code>item</code> and the resolution process terminates immediately.</p></li>
352 |  | <li>
353 |  | <p>If the referent is an HTML document and the <code>iffy:item-ref</code> DOES NOT contain a <code>guid</code> attribute, the consumer must search for an HTML <code>link</code> element whose <code>rel="alternative"</code> and whose <code>type="application/x-single-item-rss+xml"</code>. If there are no or multiple <code>link</code> elements so specified, resoluton fails. If there is a unique <code><link rel="alternative" type="application/x-single-item-rss+xml" href="..."></code>, and its referent contains RSS data with a single <code>item</code> attribute, the <code>iffy:item-ref</code> successfully resolves to that attribute.</p></li>
