		<description>[...] This is endemic of the design of the mess I alluded to in Chaos Crusher. It also flies in the face of conventional (or maybe it&#8217;s not) thought on package design: lower-level packages should be more stable than higher-level packages. [...]</description>

		<description>No problem. I think this is a really good summary on design principles, the best I&#039;ve found online. Thanks for publishing.

While I&#039;m at it, I think there&#039;s a typo in the entry about Stable Dependencies Principle:

&lt;blockquote&gt;A package should only depend upon packages that are more stable that it is.&lt;/blockquote&gt;

Should it be &quot;... stable &lt;em&gt;than&lt;/em&gt; it is.&quot;?</description>

<p>Should it be &#8220;&#8230; stable <em>than</em> it is.&#8221;?</p>

		<description>Thanks for catching in Niclas. It has been corrected. Sometimes I confuse myself more than I should while writing :-)</description>

		<description>&quot;The concrete classes, which are instable, and are expected to change, depend on the concrete classes. &quot;

Is this correct?</description>
