apex:param
A parameter for the parent component. The <apex:param> component can only be a child of the following components:
<apex:actionFunction><apex:actionSupport><apex:commandLink><apex:outputLink><apex:outputText><flow:interview>
Use this component to get user input for a controller method that does not correspond to a field on an sObject. Only <apex:inputField> and <apex:outputField> can be used with sObject fields.
Within <apex:outputText>, there’s support for the <apex:param> tag to match the syntax of the MessageFormat class in Java.
