How to set parameter in resource bundle in page

[Anthony Hong]

IN JSF page, usual do i18n like
<f:loadBundle basename="#{facesContext.application.messageBundle}"
var="tagVar"/>

then  <h:outputText value="#{tagVar.TEMPLATE_LOGIN_USER}"/>:

I have a question how to use a composite message. like
tagKey=We met for {0} days
