Section 1.8 describes the definitions.xml file as holding all of the artifacts
that are useful for configuring an SCA domain but that are not specific to a
particular composite or component. It goes on to say that "All of these
artifacts within and SCA Domain are defined in a global, SCA Domain-wide file
named definitions.xml". To achieve our extensibility goals we, in Tuscany,
consider the SCA Domain wide definitions.xml file to be a logical concept that
is constructed at runtime from the contents of definitions.xml files provided
in contributions and in Tuscany extensions.
Each definitions.xml file may contain.
* Intents
* Policy sets
* Predefined binding specifications
* Binding type descriptions
* Implementation type descriptions

h3. Add Intents and Policy Sets with an Extension
An extension, such as the modules/policy-security extension relies on some
policy sets and intents being available in the SCA Domain. The definitions.xml
is the place to define these and hence if you look in this extension module you
will find the following.
{code}
<definitions xmlns="http://www.osoa.org/xmlns/sca/1.0";
targetNamespace="http://www.osoa.org/xmlns/sca/1.0";
xmlns:sca="http://www.osoa.org/xmlns/sca/1.0";
xmlns:tuscany="http://tuscany.apache.org/xmlns/sca/1.0";>
<!-- POLICY SETS -->
<policySet name="runAs" appliesTo="sca:implementation.java"/>
<policySet name="allow" appliesTo="sca:implementation.java"/>
<policySet name="rolesAllowed" appliesTo="sca:implementation.java"/>
<policySet name="permitAll" appliesTo="sca:implementation.java"/>
<policySet name="denyAll" appliesTo="sca:implementation.java"/>
<!-- Policy Intents Defined by the SCA Runtime -->
<intent name="authentication"
constrains="sca:binding">
<description>
Specifying this intent on references requires necessary
authentication information
to be sent along with outgoing messages. Specifying
this intent on service requires
incoming messages to be authenticated
</description>
</intent>
<intent name="confidentiality"
constrains="sca:binding">
<description>
Specifying this intent requires message exchanged to be
encrypted
</description>
</intent>
<intent name="integrity"
constrains="sca:binding">
<description>
Specifying this intent requires message exchanged to be
signed
</description>
</intent>
</definitions>
{code}
When this module is loaded at runtime the contents of this file are made
generally available and hence in you composite you can use statements such at.
{code}
<component name="CalculatorServiceComponent">
<implementation.java class="calculator.CalculatorServiceImpl"/>
<reference name="addService" >
<interface.java interface="calculator.AddService" />
<binding.ws
uri="http://localhost:8080/sample-calculator-ws-secure-webapp/AddServiceComponent";
requires="authentication" />
</reference>
</component>
