Custom content models can be bootstrapped into the repository using a Spring
configuration added to the module context file.
Add the following Spring configuration to module-context.xml:
<bean id="myModule_dictionaryBootstrap" parent="dictionaryModelBootstrap" depends-on="dictionaryBootstrap">
<property name="models">
<list>
<value>alfresco/module/myModuleId/myCustomModel.xml</value>
</list>
</property>
</bean>
