Description

Composites do not propagate the instance configuration.
It should be done in order to configure sub-instances and services using composite properties.

The approach is quite simple. The composite instance configuration can be just appended to the instance and service configurations. This would allow overridding properties using composites too such as in:

<composite name="MySuperComposite">
                <instance component="my.jdbc.consumer.impl">
                               <property name="db.url" value="default-value"/>
                </instance>
                <instance component="my.other.jdbc.consumer.impl">
                               <property name="db.url" value="default-value"/>
                </instance>
</composite>

<instance component="MySuperComposite" name="msc1">
                <property name="db.url" value="jdbc://oracle..."/>
</instance>
