<p>
An SCA composite is used to assemble components in logical groupings. It is the basic unit of composition within an SCA System. An SCA Composite contains a set of Components, Services, References and the Wires that interconnect them. Composites are component implementations in higher-level composites in other words 
composites can have components that are implemented by composites. 
</p>
<p>
A composite has the following normative characteristics:
</p>
<ul>
<li>It defines a boundary for Component visibility. Components may not be directly referenced outside of the composite that contains them.</li>  
<li>It can be used as a unit of deployment. Composites are used to contribute business services to an SCA system.</li>

</ul>
