    "description": "The UIDUtil class is an all-static class with methods for working with UIDs (unique identifiers) within Flex. You do not create instances of UIDUtil; instead you simply call static methods such as the <code>UIDUtil.createUID()</code> method.  <p><b>Note</b>: If you have a dynamic object that has no [Bindable] properties (which force the object to implement the IUID interface), Flex  adds an <code>mx_internal_uid</code> property that contains a UID to the object. To avoid having this field in your dynamic object, make it [Bindable], implement the IUID interface in the object class, or set a <coded>uid</coded> property with a value.</p>",
