Dependent features are useful when a given feature depends on another feature to be installed. Such a dependency can be expressed easily in the feature definition:

<feature name="jbi">
   <feature>nmr</feature>
   ...
</feature>

The effect of such a dependency is to automatically install the required nmr feature when the jbi feature will be installed. A version range can be specified on the feature dependency:

<feature name="spring-dm">
   <feature version="[2.5.6,4)">spring</feature>
   ...
</feature>

In such a case, if no matching feature is already installed, the feature with the highest version available in the range will be installed. If a single version is specified, this version will be chosen. If nothing is specified, the highest available will be installed.
