This category is populated by pages and templates that use {{tl|ISSN}}.&lt;br /&gt;
&lt;br /&gt;
In this template, ISSN parameters are checked for invalid ISSNs as well as extraneous text such as &amp;quot;ISSN&amp;quot;, &amp;quot;N/A&amp;quot;, &amp;quot;none&amp;quot;, dashes (use hyphens instead), lower-case &amp;quot;x&amp;quot; (use &amp;quot;X&amp;quot; instead), and tab characters.&lt;br /&gt;
&lt;br /&gt;
Error messages for erroneous ISSNs look like one of:&lt;br /&gt;
&amp;lt;div class=&amp;quot;error&amp;quot;&amp;gt;&amp;lt;div class=&amp;quot;plainlist&amp;quot;&amp;gt;&lt;br /&gt;
*Invalid ISSN&lt;br /&gt;
&amp;lt;/div&amp;gt;&amp;lt;/div&amp;gt;&lt;br /&gt;
&lt;br /&gt;
