+<p>Although the basic <em>jmxbeans</em> rules give access to single JMX
attribute values in rules, a more powerful way to access
+JMX attributes is to use scripted rules, where mini-scripts can be written to
combine and check multiple values.</p>
+<p>The rule definition shown below, for example, checks two JMX attributes.
Such scripted rules can be written in any scripting language
+that Sling supports, which allows for creating rules that check JMX attributes
against other values.</p>
