class X:
  _data1 = data1 = {}
  _data2 = data2 = {}

Works, but I'm skeptical that its the best way as that leaves that
structure open to modification by python scripts.  Maybe a computed
attribute that returns _dataN.copy()?  I haven't tried that but it
might be slick.  I generally 2 step it like:

PERM = "bar"
class X:
  _foo = {}
  security.declareProtected(PERM, "getFoo")
  def getFoo(self): return self._foo.copy()

Then call it as define="foo here/getFoo" content="foo/key".
