Facelet composition Tag

                          

This is a templating tag and is used for the wrapping the content that can be included in any other facelet. This tag provides some useful features. Any content outside of this tag is left to be rendered. You can  include normal html content  in your page but Facelet will render only content that is within this tag i.e. composition tag. This tag takes one attribute named "template". This attribute is set to the path of the template where the content of this tag will be included.

Here we have written some content outside of the composition tag, that content will not be rendered.
