    This component provides a registry for Directory Factories
    <p />
    Directories are abstract representations of data sources. A
    Directory Factory represents an implementation of such data
    sources, e.g. using SQL, LDAP, etc.

      This extension point can be used to register directory
      factories.
      <p />
      The XML extension can contain an arbitrary number of factory
      declarations of the form:
      <factoryDescriptor component="org.pkg.Foo" />
      Here, Foo must be a class that implements the org.nuxeo.ecm.directory.DirectoryFactory interface
