For bean and target types, you can also refer to indexed property values. For example, each of the following is valid:

<valueof bean="/atg/Test/Person.hobbies[0]">
<valueof target="keywords[bean: /atg/Test/Person.favoriteKeyword]">

As in regular <valueof> tags in JHTML files, you can use bean: strings inside tags to refer to properties. However, you cannot use param: strings in a targeting rule’s <valueof> tag.
