  isPersistent(EStructuralFeature)
- isPersistent
  
  public static boolean isPersistent(EStructuralFeature feature)
  
  Returns true if CDO considers the given feature persistent, false otherwise.
  Note that CDO persistent is not identical to non-transient because that can be overridden with CDO_ANNOTATION_KEY_PERSISTENT. Another reason for possible deviations is that CDO considers transient references persistent if they have a persistent opposite.
  Note also that the checks for the aforementioned deviations from EStructuralFeature.isTransient() make this method somewhat expensive. Whenever possible CDOClassInfo.isPersistent() should be called instead.
