      &lt;p&gt;The platform update mechanism supports pluggable feature type
implementations. A new feature type can be registered in order
to support
alternate packaging and verification schemes.
&lt;/p&gt;
&lt;p&gt;
The &lt;code&gt;featureTypes&lt;/code&gt;
extension point allows alternate feature implementations to be
registered using a symbolic type identifier. Whenever the 
type is referenced using this identifier, the supplied factory
is used to create the correct concrete feature implementation.
&lt;/p&gt;
