apex:composition
An area of a page that includes content from a second template page. Template pages are Visualforce pages that include one or more <apex:insert> components. The <apex:composition> component names the associated template, and provides body for the template's <apex:insert> components with matching <apex:define> components. Any content outside of an <apex:composition> component is not rendered.
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.
