								<p>Although a macro can take any number of parameters, they are often no more than two or three, for readibility reasons: parameters have no name, but their position within a macro is significant.</p>
<p>If you have something like this:</p>

	<div class="CodeRay">
  <div class="code"><pre><span class="no">1</span> custom_image[test.png|50%|50%|Test Image]</pre></div>
</div>

	<p>it may still be easy enough to understand what each parameter is used for, but:</p>
<ul>
	<li>you can easily forget that the third parameter is the image width</li>
	<li>if you don&#8217;t want to resize the image, you still have to pass <em>empty parameters</em> to the macro, like this: <code>custom_image[test2.png|||Test Image]</code></li>
</ul>
<p>To avoid these situations, some macros which would normally take three or four parameters take optional attributes instead, so you can write:</p>
	<div class="CodeRay">
  <div class="code"><pre><span class="no">1</span> image[test.png
<span class="no">2</span>   @width[50%]
<span class="no">3</span>   @alt[Test Image]
<span class="no">4</span>   @height[50%]
<span class="no">5</span> ]</pre></div>
</div>

	<p>More verbose, of course, but definitely more readable. In this way, if you won't want to scale an image, you can safely omit the <code>@width</code> and <code>@height</code> attributes.</p>
	<aside class="note">
<span class="note-title">Note</span>Like parameters, attributes can contain other macros, too.
