366: <p>It is possible for paragraphs to overlap when using certain

369:
370: <pre><section>
371: <h1>My Cats</h1>
372: You can play with my cat simulator.
373: <object data="cats.sim">
374: To see the cat simulator, use one of the following links:
375: <ul>
376: <li><a href="cats.sim">Download simulator file</a>
377: <li><a href="http://sims.example.com/watch?v=LYds5xY4INU">Use online simulator</a>
378: </ul>
379: Alternatively, upgrade to the Mellblom Browser.
380: </object>
381: I'm quite proud of it.
382: </section></pre>
383:
384: <p>There are five paragraphs:</p>
385:
386: <ol class="brief"><li>The paragraph that says "You can play with my cat
387: simulator. <i title="">object</i> I'm quite proud of it.", where
388: <i title="">object</i> is the <code><a href="text-level-semantics.html#the-object-element">object</a></code> element.</li>
389:
390: <li>The paragraph that says "To see the cat simulator, use one of
391: the following links:".</li>
392:
393: <li>The paragraph that says "Download simulator file".</li>
394:
395: <li>The paragraph that says "Use online simulator".</li>
396:
397: <li>The paragraph that says "Alternatively, upgrade to the Mellblom Browser.".</li>
398:
399: </ol><p>The first paragraph is overlapped by the other four. A user
400: agent that supports the "cats.sim" resource will only show the
401: first one, but a user agent that shows the fallback will
402: confusingly show the first sentence of the first paragraph as
403: if it was in the same paragraph as the second one, and will show
404: the last paragraph as if it was at the start of the second sentence
405: of the first paragraph.</p>
406:
407: <p>To avoid this confusion, explicit <code><a href="semantics.html#the-p-element">p</a></code> elements can be
408: used.</p>
