      &lt;p&gt;
The platform update mechanism supports pluggable site type
implementations. A new site type can be registered in order
to support
alternate site layout schemes.
&lt;/p&gt;

&lt;p&gt;
The &lt;code&gt;siteTypes&lt;/code&gt;
extension point allows alternate site 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 site implementation.
&lt;/p&gt;
