is there a way to register a factory in Unity's XML configuration?

Is there a way to register a factory in Unity's XML configuration? Unity should inject some constructor parameters and use the factory in order to instantiate the object.

Here is a Spring .NET based example:

<object id="name" type="Namespace.Factory, Assembly" factory-method="Create">
   <constructor-arg name="intParam" value="1" />
   <constructor-arg name="objParam" ref="objectName" />
</object>

Many thanks in advance!
