Targetable messages with severity levels

We sometimes need to target a FacesMessage instance to a specific component. For example, suppose we have p:growl and p:messages/p:message tags on the same page and need to display some messages as p:growl and some as p:message. PrimeFaces has a grouping feature for messages to associate a notification component to specific command components so that messages created as a result of an action will be displayed in the associated messages or the growl tags.

<h:panelGroup id="msg1">
