<p>Set, change or delete properties of a message, flow context or global context.</p>
<p>The node can specify multiple rules that will be applied in turn.</p>
<p>The available operations are:</p>
<ul>
<li><b>Set</b> - set a property. The value can be a variety of different types, or
can be taken from an existing message or context property.</li>
<li><b>Change</b> - search &amp; replace parts of the property. If regular expressions
are enabled, the <b>replace with</b> property can include capture groups, for example <code>$1</code></li>
<li><b>Delete</b> - delete a property.</li>
