a simple attribute is not a property in the sense Robin meant it,
and a "data property" is even more specific. See

    http://docs.python.org/ref/descriptor-invocation.html

 Help on class property in module __builtin__:

 class property(object)
  |  property(fget=None, fset=None, fdel=None, doc=None) -> property attribute
  |
  |  fget is a function to be used for getting an attribute value, and likewise
  |  fset is a function for setting, and fdel a function for del'ing, an
  |  attribute.  Typical use is to define a managed attribute x:
  |  class C(object):
  |      def getx(self): return self.__x
  |      def setx(self, value): self.__x = value
  |      def delx(self): del self.__x
  |      x = property(getx, setx, delx, "I'm the 'x' property.")
