The "it" above may be misleading:

  It is very unlikely that a non-persistent object has a "_p_changed"
  method.

  The "it" above therefore cannot refer to the 'object not derived
  from "Persistent"'.

  Usually, "it" refers to the persistent parent containing the
  non persistent object as attribute value.
