          An action&apos;s enablement and/or visibility can be defined using the elements &lt;samp&gt;enablement&lt;/samp&gt; and &lt;samp&gt;visibility&lt;/samp&gt; respectively. These two elements contain a boolean expression that is evaluated to determine the enablement and/or visibility.
 &lt;p&gt;
 The syntax is the same for the &lt;samp&gt;enablement&lt;/samp&gt; and &lt;samp&gt;visibility&lt;/samp&gt; elements. Both contain only one boolean expression sub-element. In the simplest case, this will be an &lt;samp&gt;objectClass&lt;/samp&gt;, &lt;samp&gt;objectState&lt;/samp&gt;, &lt;samp&gt;pluginState&lt;/samp&gt;, or &lt;samp&gt;systemProperty&lt;/samp&gt; element. In the more complex case, the &lt;samp&gt;and&lt;/samp&gt;, &lt;samp&gt;or&lt;/samp&gt;, and &lt;samp&gt;not&lt;/samp&gt; elements can be combined to form a boolean expression. Both the &lt;samp&gt;and&lt;/samp&gt;, and &lt;samp&gt;or&lt;/samp&gt; elements must contain 2 sub-elements. The &lt;samp&gt;not&lt;/samp&gt; element must contain only 1 sub-element.
