<DD><B>Description copied from interface: <CODE><A HREF="../../../../org/geotools/feature/FeatureType.html" title="interface in org.geotools.feature">FeatureType</A></CODE></B></DD>
<DD>Creates a new feature, with a generated unique featureID.
 <p>
 Generating a FeatureID is less than ideal, as a FeatureID should be something
 special about the "real world object" being modeled as a feature.
 <p>
 As an example: the "Effiel Tower" is a great feature id (there is only one) and we can
 use that Feature ID in serveral systems:
 <ul>
 <li>In a tour guide FeatureTypes one which records (NAME, LOCATION, COST); and
 <li>In a historical reference (NAME, LOCATION, HIEGHT, DATE, HISTORY)
 </ul>
 <p>
 Explicitly a FeatureID should be persistant over time, and between systems.
 <p>
 The FeatureIDs "generated" by this method are generally created by a datasource.
 This method is more for testing that doesn't need featureID.
 </p>
 <p>
 Warning: This class does not follow the geotools guidelines of sepearting out
 Interface from Factory, in geotools 2.3 there will be a formal FeatureFactory
 allowing you to provide application specific FeatureImplementations as an orthogonal
 concern to definition of type.
