apex:variable
A local variable that can be used as a replacement for a specified expression within the body of the component. Use <apex:variable> to reduce repetitive and verbose expressions within a page.
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.
Note: <apex:variable> does not support reassignment inside of an iteration component, such as <apex:dataTable> or <apex:repeat>. The result of doing so, e.g., incrementing the <apex:variable> as a counter, is unsupported and undefined.
