<p>In HTML a <code>&</code> marks the begin of a reference, either of a character reference or of an entity reference. From that point on the parser expects either a <code>#</code> denoting a character reference, or an entity name denoting an entity reference, both followed by a <code>;</code>. That’s the normal behavior.</p>
<p>But if the reference name or just the reference opening <code>&</code> is followed by a white space or other delimiters like <code>"</code>, <code>'</code>, <code><</code>, <code>></code>, <code>&</code>, the ending <code>;</code> and even a reference to represent a plain <code>&</code> can be omitted:</p>
<pre><code><p title="&">foo & bar</p>
<p title="&">foo & bar</p>
<p title="&">foo & bar</p>
</code></pre>
<p>Only in these cases the ending <code>;</code> or even the reference itself can be omitted (at least in HTML 4). I think HTML 5 requires the ending <code>;</code>.</p>
<p>But the specification recommends to always use a reference like the character reference <code>&</code> or the entity reference <code>&</code> to avoid confusion:</p>
<blockquote>
<p>Authors should use "<code>&</code>" (ASCII decimal 38) instead of "<code>&</code>" to avoid confusion with the beginning of a character reference (entity reference open delimiter). Authors should also use "<code>&</code>" in attribute values since character references are allowed within CDATA attribute values.</p>
</blockquote>
