[Zope] Separate data from control automatically

[Sin Hang Kin]

Is it possible for zope to separate control from data automatically?

To make the best use of Zope, it will be necessary to separate the data and
control.

with XML, DOM will assign id for each node and thus  all of them can be
refered by that id.

Is it possible for zope to perform this? Will a modify of  load_site able to
do this semi-automatically? (run load_site over an existing zope tree?)
