Facelet component Tag

        

This tag is used to add a new component into the JSF component tree as children of UI component instance. This tag shows its behavior like composition tag. The difference is that the component tag inserts a new UIcomponent instance in the component tree and this instance is the root of all its child components or fragments. The content outside of the tag is ignored as it happens with composition tag.
